) sounded together. If you speak of only two notes that are to be sounded then that is known as an interval (like a distance). in the photos using sticky notes on a keyboard below... but C shown as three notes on lines of sheet music would not show that concept. Notice the simpler of three-note chords are the major chords "C, F, and G" that are made up of only white keys spaced and shaped exactly the same way "every time." That shape (like a formula) uses fingers "5, 3, and 1". The other 3-note major chords use the same fingering but slightly differing shapes because of sharps and/or flats: Find the fundamental note (C or F or G), and Go across the ivory keys to the 3rd note using the 3rd finger and And the ivory 5th note using the 5th finger (the thumb). So, the formula for those three chords is simply left to right on the left hand (numbered 5, 3, 1) starting at the fundamental basis note which names of each chord. Notice that "D chord" is exactly the same shape as "A chord" in the photos using sticky notes on a keyboard at the left... but D shown as three notes on lines of sheet music does not show that idea as clearly. Examine the shapes of the hand for A and D chord and you'll agrees that they are almost the same as C, F, G -- but it has the middle fingered-note "sharped" ("Sharping" or "flatting" is really only a half step between notes.). So, these both have a black key for the middle finger -- left to right on the left hand (5, 3#, 1) where the "#" symbol means "sharp" which is most often the black key to the right... The flat is merely adjacent to the left side of a note and sharp would be adjacent to the right side of the same key, but either way is a 1/2 step off. "5, 4, 3, 2, 1 ~ 1, 2, 3, 4, 5" From LEFT to RIGHT (so, no keyboard is needed for this kind of practice!): Left-hand: "5, 4, 3, 2, 1" Right-hand "1, 2, 3, 4, 5"Left-hand: "5, 3, 1" Right-hand "1, 3, 5", and such. So, you can have a fake-board the size of real keys or keyboard -- but remember that some electronic boards are shortened, not full piano size (they have fewer octaves -- fewer black and white keys).

One-sentence summary -- Realize that chords generally consist of at least "three" notes/pitches/tones (Let's call them notes. Compare chords: notice C chord is exactly the same shape as F and G chords Visualize the shape of the left hand for "C, F, and G" is all the same identical tri-formation. Realize the situations where two ivory keys are together (adjacent, without a black one between them) -- so there the white key is the sharp -- or the flat (just 1/2 step to the "other" side) in some chords and scales. Flat a note in a similar way compared to sharping, but flatting is moving left (down) a half step in the flow of the music. Understand that the combination for a chord of three (or more) notes sounded together at certain distances between the notes ("intervals") are based on a pattern (or formula) for the chord in the "circle of notes" like find your "1st, 3rd, 5th" any or all of which may be off by half steps either way (sharped leftward or flatted rightward on the keyboard) to form various chords. Play the same chord on the right hand with the same kind of shape with the thumb and fingers again numbered left to right "1, 2, 3, 4, 5" but now starting from the thumb (1) to the right little finger (5); and though it looks opposite -- just ignore the thumb and finger switching, and so it is still the "same" kind of shaped tripod Practice the numbering by "air piano" (on a table), moving your fingers while thinking: Get or (accurately) draw a partial or full-"model", paper keyboard to use, if you have no actual keyboard.

Mix tablespoon (3.7 ml) of baking soda with one or two drops of water to form a paste. Make sure the paste is not too watery, as this will decrease the paste's cleaning power. The paste should be relatively dry, but not powdery. Look for a toothpaste-like consistency. Use a clean, cotton cloth to rub a pea-sized amount of paste onto your pieces of silver. Rub the silver in a straight back and forth motion until you see the shine return. As you clean your silver, it is normal for the baking soda paste to turn grey. Do this by diluting your paste with a couple more drops of water. Then dip your toothbrush into the diluted paste and scrub the smaller crevices. Alternatively, you can use a Q-tip to clean small crevices if you do not have a spare toothbrush. Do this once all the tarnish is removed. Dry the silver with a soft, cotton cloth like a dishtowel or with a Selvyt cloth. Finish by polishing the item with a microfiber cloth.
