prompter: Which notes harmonize with E and what might be a good note to play outside of the key of E for a dissonant effect?

assistant: The notes that harmonize with the key of E major are:

-   E - the tonic or keynote
-   G# - the major 3rd above E
-   B - the perfect 5th above E
-   D# - the major 7th above E

To achieve a dissonant, outside-the-key effect, you could play:

-   F or F# - a minor 2nd or major 2nd interval above E, which would create a dissonant clash
-   A - a minor 6th interval above E, which is also dissonant and outside the key of E major

Playing notes a semitone or whole tone away from the notes in the key of E will create tension and dissonance. The further away from the key you get, the more discordant the effect.

prompter: What are some examples of songs that use this successfully

assistant: There are many songs that use dissonance and tension to great effect, which include:

1. "Purple Haze" by Jimi Hendrix - This song features a guitar riff that frequently uses the dissonant interval of a tritone (augmented fourth/diminished fifth), which creates a sense of tension and unease throughout the song.

2. "Paranoid Android" by Radiohead - This song uses dissonant chords and intervals throughout to create a sense of unease and disorientation. The guitar riff in the intro, for example, features a dissonant interval between the notes G and F#.

3. "The End" by The Doors - The guitar solo in this song features many dissonant and outside-the-key notes, including a prominent use of the blues scale which incorporates the flat 5th interval.

4. "Sweet Child O' Mine" by Guns N' Roses - The iconic intro riff to this song features a dissonant interval between the notes B and C, which helps to create a sense of tension and anticipation before the song kicks in.

5. "Symphony No. 5" by Beethoven - The famous opening four-note motif of this symphony features a dissonant interval between the third and fourth notes, which helps to create a sense of tension and drama throughout the piece.

assistant: Some examples of songs that use dissonance and outside-the-key notes effectively include:

- "Purple Haze" by Jimi Hendrix: The guitar riff in the song makes use of the flat fifth, which creates a tritone interval that is highly dissonant and creates a sense of tension.
- "Bohemian Rhapsody" by Queen: The operatic section of the song features a chord progression that includes an augmented chord, which is made up of two major thirds and creates a highly dissonant sound.
- "The Man Who Sold the World" by David Bowie: The guitar riff in the song makes use of a flattened seventh note, which creates a sense of tension and dissonance.
- "Tomorrow Never Knows" by The Beatles: The song features a drone-like sound created by a single chord, and includes elements of Indian music that make use of dissonant intervals and unusual scales.

These are just a few examples, but there are countless songs that make use of dissonance and outside-the-key notes to create interesting and unique sounds.

assistant: harmonic chord:

G+C+E


harmonic notes:

E (the tonic)
F# (the major 2nd)
G# (the major 3rd)
A (the perfect 4th)
B (the perfect 5th)
C# (the major 6th)
D# (the major 7th)

Dissonant notes:

 F, which is not part of the E major scale. F is a half-step lower than the F# in the E major scale and creates a dissonant, tense sound when played against an E major chord or melody. Other notes that can create dissonant effects when played against an E major chord or melody include Bb and Ab, which are also outside of the E major scale.

prompter: Write a melody that switches from pure E major in the first three measures to E major with a dissonant F instead of an F#. Please use ABC notation in a code block.

assistant: Sure, here's a simple melody that switches from pure E major to E major with a dissonant F:

``` 
X:1
T: E Major Melody
M:4/4
L:1/4
K:E
|: E2 G2 A2 | B2 B2 B2 | E2 G2 A2 | F2 F2 F2 |
E2 G2 A2 | B2 B2 B2 | E2 G2 A2 | F2 F2 F2 :|
``` 
In the first three measures, the melody follows a simple arpeggio of the E major chord, with the notes E, G#, and B played in sequence. In the fourth measure, the F# is replaced with F, which creates a dissonant effect.
