# Harmonica/Advanced Chords

While the true chords provided by harmonica is very limited, a player can play any chords as an arpeggio; that is to play the notes of the chord one after another. That being said, combined with the fact that some of the notes are close together and at the same direction already, allow one to play chords and rhythm easily.
For example, On a C chromatic, in addition to the native C major chord and D-minor-7th chord:
* G Major chord: blowing the hole 3, then draw on 4 and 5.
* F major chord: drawing on hole 2 and 3, then blow on 4. F major-7th chord can thus be construct with the addition of blowing hole 5 too.
However, some musicians, especially blues musicians, merely "suggest" the chord. For example, even in second position on a blues harp, there's no dominant-major (V) chords available (in the case of a C harp, the D major chord). So what they did are the following:
* An octave on 1-4 draw to suggest V-chord
* A 4-5 draw (D-F) to suggest a maj7 chord rooted on the V.
Some will also do that for other chords even if it's available... For example, for G major chord on C diatonic, play only B-D (draw hole 3 and 4)
In terms of playing as a rhythm section, one approximate the chord by playing the notes of the chord in succession: for example, on a chromatic, when playing a G maj7th, one can go like this:
Also, even with arpeggio, and have access to all the notes of the chords, a blues/jazz musician may not even play all notes of the rhytmn. For example, a standard 12-Bar blues have the following:
May be played like this:
Note that this use a normal major chord to simulate a seventh chord.
# Harmonica/Basic Chords

All diatonics, tremolo, and chromatics are capable of true chords (i.e. all the notes sounded at the same time); however, the chords may not be appropriate for the music you are playing.
Diatonics are specifically designed with chording in mind, and such, it lacks the 4th, 6th, and 7th notes in the bottom octave. As such, the chords available are the following:
* Straight harp:
** I chord, all on blows holes 1-3, 4-6, 7-9.
** ii chord, on draw hole 4-6
** V chord, on draw hole 2-4
** V7 chord, on draw hole 2-5
** vii° chord, on draw hole 3-5
* Cross harp:
** I chord, on draw hole 2-4
** I7 chord, on draw hole 2-5
** iii° chord, on draw hole 3-5
** IV chord, all on blows holes 1-3, 4-6, 7-9.
** v chord, on draw hole 4-6
European Tremolos also have the same number of chords available.
* Third position
* I-major on draw hole 4-6
* IV-major on draw hole 2-4
Chromatics, which usually is played in the key of C, have the following chords available:
* I chord, all on blow hole 1-3, 5-7, 9-11
* ii chord, all on draw hole 1-3, 5-7, 9-11
* vii7-minor chord, all on draw hole 4-7 and 8-11
East Asian Tremolos also have the same number of chords available.
Of course, one can attempt to bring about more chords with bending techniques; this is especially common in cross-harp playing.
# Harmonica/Bending

Bending notes is, without a doubt, the most important technique in harmonica playing. It adds that special bluesy something to your play, and allows you to play semi-chromatically on a normally diatonic instrument - especially in second position.
However, due to the unique, soulful sound generated by bending, you should learn how to bend notes even if you're playing a chromatic harmonica. On a chromatic harmonica, all holes that have windsavers can bend in both draw and blow; typically, this means all holes except for the higher octaves (hole 8 to 12), which can only draw bend on hole 8-11, and blow bend on hole 12.
On a diatonic harmonica, hole 1-6 can draw bend, and hole 7-10 can blow bend.
A player can bend the pitch of the higher tuned reed down toward the pitch of the lower tuned reed in any given hole. In other words, on a diatonic harmonica, on holes 1 through 6, the draw notes can be bent, and on holes 7 through 10, the blow notes can be bent. Hole 3 allows for the most dramatic bending: On a C harmonica, it is possible to draw bend hole 3 from a B down to a G#, or anywhere in between. The physics of bending are quite complex, but amount to this: the technique "pinches" the air and thus changes the pressure of the airflow.
How to do a bend:
* Draw: This can be done by lowering the jaw, while raising the back of the tongue, focusing the air flow at the back of the tongue. If you want to, let the tip of the tongue touch the spot where the tenon meets the bottom of the mouth cavity.
* Blow: This is done by lowering the jaw, while raising the front of the tongue slightly, focusing the air flow at just slightly behind the teeth.
Bends are essential for blues and rock harmonica due to the soulful sound they add to the instrument - the famous "wail" of the blues harp typically requires bending. Luckily, this can be done on all kinds of harmonicas; as Stevie Wonder has shown, one can even do it on a chromatic harmonica.
Those that want to be able to use any harmonica as a chromatic instrument should also learn to overbend.
# Harmonica/Basic Maintainence and Care

If you actually know your stuff, you will know that a good quality harmonica is gonna cost way more than a few dollars... especially a chromatic, which is $100 or more. Even though most harmonicas have good manufacturing, proper maintenance and preventative measures are still needed. Aside from the cost of repairs, you might have difficulty finding someone skilled enough to repair your harmonica, especially if you are not good at repairing!
       A very good homemade case can be made by the Pelican waterproof cases. Note that Microcase usually do not come with the lining.
          microcase 1040/1050 is good for 12-hole chromatic
          microcase 1060 is good for 16-hole chromatics
* Avoid extreme temperatures. While your plastic comb should be somewhat tolerant to temperature, your wood comb definitely isn't; since it's already subjected to swelling and shrinking at room temperature, don't even encourage it more by using those.
* Avoid dust and other particles. Dust will interfere with the movements of the reed, making it sound weird. Of course, make sure there are no food particles in your mouth either.
* Avoid excess moisture. Obvious for wood comb (it swell and shrink), but all chromatics are affected, as they have windsavers. Thus, never dunk your harmonica into water/beer/liquid etc. Even if it's a plastic-comb harp with no windsavers, the reedplate, reed, bolt and/or screws may rust.
* Clear any moisture if possible. Most of the moisture actually comes from your mouth. After playing, shake the harmonica a little bit,, pat it against your palm softly, and wipe it clean with a cloth.
* Avoid the beach if possible. The salty air can cause the reeds to rust rapidly.

## Routine cleaning

* After playing, shake the harmonica a little bit, pat it against your palm softly, and wipe it clean with a cloth.
* Once in a while, use alcohol and cotton balls to clean the mouthpiece and cover.

## Advanced cleaning
### Cleaning the mouthpiece/slide package

Unless we all decided to use Tombo's S-50, the slide package is a blessing and curse at the same time. When it works, it's a blessing, as we can do quick chromatic runs and slide-based effects. when it doesn't... well, no amount of musicianship can save you as your slide move slowly, or even worse, stopped completely!
Thus, we all have to take it apart, from time to time.

#### Warnings

* Slide packages ARE made up of a few tiny but crucial pieces. Do it on a flat table with ample lighting.
* Slide packages are just as fragile if not more fragile than the reed plates. Always prepare your work surface before you do anything.

#### Tools needed

* Screwdriver. Preferably a precision version.
* Microfiber cloth
* Rubbing Alcohol To clean off any old grime
* Lubricant The lubricant has a twofold purpose. Obviously, it is supposed to make your slide slide easier, but it also does some sealing, which helps maintain your slide. Franz Chmel recommended paraffin oil, but I personally use Vaseline mainly because it's safer.
# Guide to Game Development/Theory/Mathematics/Trigonometry/The basic identities applied to right angle triangles
## Opposite, Adjacent and Hypotenuse

When you have a right-angled triangle, and you decide on one of the 2 non-right-angled angles, you can then decide on what the names of the sides are.

## S$^o$h C$^a$h T$^o$a

S$^o$h C$^a$h T$^o$a is an acronym to help you remember how you can use your knowledge of opposites, adjacents and hypotenuses to find extra pieces of information on a right-angled triangle. Written out as three equations, it looks like:
$\sin(\theta )={\frac {Opposite}{Hypotenuse}}$
$\cos(\theta )={\frac {Adjacent}{Hypotenuse}}$
$\tan(\theta )={\frac {Opposite}{Adjacent}}$
Using these three equations, if you were given two pieces of information (as long as they're both NOT angles), you can any other piece of information on the triangle. Note: the Greek letter, $\theta$ is often used with angles to mean, "an unknown angle."

### Inverse trigonometry

There are three main inverse trigonometric functions: $\sin ^{-1},\cos ^{-1}$ and $\tan ^{-1}$.
If the trigonometric function with an angle gives you a value, then the inverse trigonometric function of the value, will give you the angle.
* Example questions
* For the following triangle, find x.
* Answer:
* $\tan(60^{\circ })={\frac {4}{x}}$
* $x={\frac {4}{\tan(60^{\circ })}}$
* Use your calculator...
* $x={\frac {4{\sqrt {3}}}{3}}\approx 2.31$
* For the following triangle, find x.
* Answer:
* $\cos(12^{\circ })={\frac {8}{x}}$
* $x={\frac {8}{\cos(12^{\circ })}}$
* Use your calculator...
* $x\approx 8.18$
* For the following triangle, find x.
* Answer:
* $\sin(30^{\circ })={\frac {8}{x}}$
* $x={\frac {8}{\sin(30^{\circ })}}$
* You could use calculator, but $\sin(30^{\circ })={\frac {1}{2}}$, so you don't need to.
* $x=16$
* For the following triangle, find θ.
* Answer:
* $\sin(\theta )={\frac {3}{5}}$
* $\theta =\sin ^{-1}{\bigg{\frac {3}{5}}{\bigg )}$
* Use your calculator...
* $\theta \approx 36.9^{\circ }$
* For the following triangle, find θ.
* Answer:
* As you've been given three sides, there are three ways to do this. I'm only going to show one way, but they will all get the same answer.
* $\tan(\theta )={\frac {12}{5}}$
* $\theta =\tan ^{-1}{\bigg{\frac {12}{5}}{\bigg )}$
* Use your calculator...
* $\theta \approx 67.4^{\circ }$
* For the following triangle, find x and θ.
* Answer:
* As the angles in a triangle add up to 180, and the to unknown angles are the same, then you can tell that $\theta =45^{\circ }$. As for the sides, they are also equal, this means you could use a rearranged version of the Pythagorean theorem ($2x^{2}=10^{2}$). But as this is about trigonometry, I'm going to do it that way. I could pick any of sin, cos and tan, also I could pick any one of the two angles. I'll go with cos and the bottom left angle.
* $\cos(45^{\circ })={\frac {x}{10}}$
* $x=10\cos(45^{\circ })$
* You could use your calculator, but you can also get it in surd form without.
* $x={\frac {10{\sqrt {2}}}{2}}=5{\sqrt {2}}\approx 7.07$

# Guide to Game Development/Theory/Mathematics/Trigonometry/Trigonometry used with non-right angles

For non-right-angled triangles, there are two rules that you can use:
For finding sides: ${\frac {a}{\sin(A)}}={\frac {b}{\sin(B)}}={\frac {c}{\sin(C)}}$
Rearranged for finding angles: ${\frac {\sin(A)}{a}}={\frac {\sin(B)}{b}}={\frac {\sin(C)}{c}}$
For finding sides: $a^{2}=b^{2}+c^{2}-2bc\cos(A)$ $b^{2}=a^{2}+c^{2}-2ac\cos(B)$ $c^{2}=a^{2}+b^{2}-2ab\cos(C)$
Rearranged for finding angles: $\cos(A)={\frac {b^{2}+c^{2}-a^{2}}{2bc}}$
$\cos(B)={\frac {a^{2}+c^{2}-b^{2}}{2ac}}$
$\cos(C)={\frac {a^{2}+b^{2}-c^{2}}{2ab}}$

# Guide to Game Development/Theory/Mathematics/Trigonometry/Degrees Vs Radians Vs Gradians

Degrees, radians and gradians are all different ways of measuring angles, and there isn't a standard, they all have their uses and so all of them are used.

## Degrees

Degrees are denoted by the symbol: °.
Degrees measure angles where a right-angle is 90°, this means that a line has an angle of 180° and that a circle has an angle of 360°.

## Radians

Radians can be denoted by the symbol: $^r$, but often no symbol is used.
The greek letter pi (π) has been used as a constant of the ratio of a circle's circumference to its diameter. $\pi \approx 3.1415926536$.
Radians measure angles where a right-angle is ${\frac {\pi }{2}}$, this means that a line has an angle of $\pi$ and that a circle has an angle of $2\pi$.
As $2\pi$ is a bit of a weird number for a full circle, the greek letter tau (τ) is often used to mean $2\pi$. $\tau \approx 6.2831853072$. The benefit of using this new constant is that now a right angle (a quarter of a circle) is ${\frac {\tau }{4}}$, half of the circle is ${\frac {\tau }{2}}$, three-quarters of a circle is ${\frac {3\tau }{4}}$ and a full circle is $\tau$. As this isn't the standard, throughout this book π will be used instead.

## Gradians

Gradians are denoted by the symbol: $^g$.
Gradians are only used in continental Europe.
Gradians measure angles where a right-angle is 100$^g$, this means that a line has an angle of 200$^g$ and that a circle has an angle of 400$^g$.

## Converting between them

| Degrees | Radians | Gradians |
| $x^{\circ }$ | $x{\frac {\pi }{180}}$ | ${x{\frac {10}{9}}}^{g}$ |
| ${x{\frac {180}{\pi }}}^{\circ }$ | $x$ | ${x{\frac {200}{\pi }}}^{g}$ |
| ${x{\frac {9}{10}}}^{\circ }$ | $x{\frac {\pi }{200}}$ | $x^{g}$ |
| 1° | ${\frac {\pi }{180}}$ | 1.111...$^g$ |
| 30° | ${\frac {\pi }{6}}$ | 33.333...$^g$ |
| 45° | ${\frac {\pi }{4}}$ | 50$^g$ |
| 60° | ${\frac {\pi }{3}}$ | 66.666...$^g$ |
| 90° | ${\frac {\pi }{2}}$ | 100$^g$ |
| 180° | $\pi$ | 200$^g$ |
| 270° | ${\frac {3\pi }{2}}$ | 300$^g$ |
| 360° | $2\pi$ | 400$^g$ |

# Maya 3D: Zero to Hero/Base Command Overview

Let's make a quick overview of the basic command needed, for further learning I recommend watching the shortcut list in resources.

## Navigation

You can navigate inside the 3d view using the ALT button and the mouse:
* ALT + MouseLeft = Rotate view
* ALT + MouseMiddle = Pan
* ALT + MouseRight = Zoom

## Selection

Select with MouseLeft, using SHIFT it's possible to add or subtract objects from the selection, CTRL will deselect only while SHIFT+CTRL will have the opposite effect allowing only to select. There are various modes to selection based un what you desire to select:
* F8 will toggle between Object Mode where you select whole objects and whatever mode where you previously in.
* F9 enters Vertex Mode where you select the single points the form the 3d object
* F10 enters Edge Mode where you select the linees colligating vertex to each other
* F11 enters Face Mode where you select the faces described by the edges
* F12 enters UV Mode which is used for textures

## Edit

That's easy, just remember QWERTY
* Q is the normal selection tool
* W will let you move things around
* E is for rotating
* R for scaling
The others are unimportant for now, let's go with a quick tutorial so we don't get too bored.

## About This Book

Most of those here interested in 3d modelling probabily already know the featured book Blender 3d: Noob to Pro, it's a wonderful piece of work that helped me learn a lot, so I wanted to pass the love around by making an effort towards making a structured way to learn one of the big beast in the 3d panorama: Maya 3d. To do so I intend, whenever possible, to go over the point made by Blender: Noob to Pro and translating them into Maya, it may not be the best approach for a standalone book but as long as I'm going to write this alone it's my best bet to complete this project in the speediest manner possible, but I sincerely hope that others will come to help me in this frankly enormous endeavour. Without further ado let's begin.

## Useful resources

Autodesk: this is the website of the company producing Maya, you may download a 3 year educational license for Maya (or any other program made by Autodesk) simply by signing in, the only limitation in the educational software is an annoying banner when you save, a more than fair bargain if you ask me. Autodesk learning pages: quite a bit of help for both beginners and the not so beginners.

# Mazda Guide/Auxmod

I don't think the AuxMod has seen any development recently, I don't even know if it is still being used by anyone. But for the sake of argument, here is the information about the mod.

## Explanation

* AuxMod is a circuit board that connects to your factory stereo and makes use of the Tape/MD player
* It converts the Tape/MD player to an input port (3.5mm RCA mini)
* With this input port you can play mp3 players or anything that has a standard headphone port through the factory stereo
* Successfully tested with the RX-8, Mazda6, Mazda5, Mazda3, Miata, MPV, Tribute and Mazda2 (according to the website)
** I believe Protege 5 has been successfully tested, although no official word from the developer
