On the staff

EF♯G♯ABC♯DE

On a treble staff, the E dominant 7th arpeggio is written E G♯ B D.

The solid notes are the E dominant 7th arpeggio. The pale notes are the rest of E mixolydian, the larger scale it is carved out of, so you can see which notes it leaves out.

Why the E dominant 7th arpeggio has this sharp

  1. E1
  2. 4
  3. G♯3
  4. T+S
  5. B5
  6. T+S
  7. D♭7
  8. T
  9. E8

A scale is a pattern of steps, and this one is 4 T+S T+S T: 4, a tone and a half, a tone and a half, and so on. T stands for a tone, which is two semitones. T+S stands for a tone and a half, which is three semitones. 4 stands for a step of four semitones. The pattern is what gives E dominant 7th its sound, and it stays the same whichever note you start on.

This scale has only four notes, so it does not use every letter. It is built on E mixolydian, and the notes it shares are spelled the same way as they are there.

The pattern still does not fit the plain letters. If you walk the pattern up from E, one letter cannot keep up:

  • G♯ — the third. The pattern needs 4 from E, but E to G is only a tone and a half, so G has to rise to G♯.

That accidental was not a choice. Once you pick the note to start on, the pattern decides the rest, and a key signature is a record of the result.

The E dominant 7th arpeggio is written with G♯, because the 4 T+S T+S T pattern of steps cannot be spelled with plain letters from E.

The pattern of steps is the part of a scale that never changes. The letter names take sharps or flats to fit that pattern, and a key signature is a record of those sharps or flats.

The keyboard shows the same four notes as a shape you can see. The coloured keys are the E dominant 7th arpeggio, the pale keys are the rest of E mixolydian, and you can click any key to hear it.

The E dominant 7th arpeggio has four playable positions, at frets 2–6, 6–10, 9–13 and 12–16.

Each shape starts on a different degree of the scale and fits inside five frets, so your hand can play all of it without moving.

One climb up the neck

DADGAD23456789101112131415135♭7135♭7135♭71TAB26257697911141214

The climb runs from fret 2 to fret 14 and plays thirteen notes.

This is one path from the lowest root to the top of the neck, and it plays each note once, never on two strings. It takes a different number of notes on different strings. The widest stretch on any one string is five frets.
