Arpeggios

Arpeggio: chord tones played one at a time instead of simultaneously

Chord:    C E G     (played together)
Arpeggio: C-E-G     (played sequentially)

Why arpeggios matter:
  They outline harmony — you hear the chord through single notes
  Improvisation: arpeggios target chord tones precisely
  Technique: develops finger independence and position awareness

Major:        1 - 3 - 5         (C-E-G)
Minor:        1 - b3 - 5        (C-Eb-G)
Diminished:   1 - b3 - b5       (C-Eb-Gb)
Augmented:    1 - 3 - #5        (C-E-G#)

Major 7th:    1 - 3 - 5 - 7     (C-E-G-B)
Dominant 7th: 1 - 3 - 5 - b7    (C-E-G-Bb)
Minor 7th:    1 - b3 - 5 - b7   (C-Eb-G-Bb)
Dim 7th:      1 - b3 - b5 - bb7 (C-Eb-Gb-A)

Root position:   1 - 3 - 5 - 8         (ascending)
First inversion: 3 - 5 - 8 - 10        (start on 3rd)
Second inversion: 5 - 8 - 10 - 12      (start on 5th)

Extended patterns:
  1 - 3 - 5 - 8 - 5 - 3 - 1           (up and down)
  1 - 3 - 5 - 3 - 5 - 8 - 5 - 3       (rolling)
  1 - 5 - 3 - 8                        (broken pattern)

Through chord changes (ii-V-I in C):
  Dm7:  D - F - A - C
  G7:   G - B - D - F
  Cmaj7: C - E - G - B
  Connect by finding nearest chord tone in next arpeggio

Classical:
  Alberti bass: broken chord pattern (1-5-3-5)
  Accompaniment figures in piano/guitar
  Harp glissando is essentially an arpeggio

Jazz:
  Target chord tones on strong beats
  Approach notes: half step above or below target
  Enclosure: surround target with notes above and below

DJ/Production:
  Arpeggiator: synth plugin that cycles through chord notes
  Rate: sync to BPM (1/8, 1/16, etc.)
  Patterns: up, down, up-down, random, played order
  Classic sounds: vintage synth arpeggios, trance leads
