On the staff

CDEFGAB♭C

On a treble staff, the C mixolydian scale is written C D E F G A B♭.

This is one octave of the C mixolydian scale, written on the treble clef. Guitar and bass music is written an octave higher than it sounds, and the small 8 under the clef is the sign for that.

A scale is a pattern of steps, and this one is T T S T T S T: a tone, a tone, a semitone, and so on. S stands for a semitone, the distance of one fret or one key. T stands for a tone, which is two semitones. The pattern is what gives C mixolydian its sound, and it stays the same whichever note you start on.

The second rule is that a seven-note scale uses each letter name once, from A to G, so its seven notes take seven different letters. That is why C mixolydian is spelled the way it is, rather than with whichever accidental looks tidier.

Together, the two rules leave no room for choice. If you walk the pattern up from C, one letter cannot keep up:

  • B♭ — the flat seventh. The pattern needs a semitone from A, but A to B is only a tone, so B has to fall to B♭.

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 C mixolydian scale is written with B♭, because the T T S T T S T pattern of steps cannot be spelled with plain letters from C.

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.

103 notes of the C mixolydian scale are marked across seven strings.

This is every place the notes of the C mixolydian scale fall on the 7-string guitar, with each note's name and its scale degree. The roots are marked so you can find your bearings.

The C mixolydian scale has seven playable positions, at frets 1–5, 3–7, 5–9, 6–10, 8–12, 10–14 and 11–15.

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

The climb runs from fret 1 to fret 17 and plays 27 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.
