On the staff

BCDEFGAB

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

This is one octave of the B locrian 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 S T T S T T T: a semitone, a tone, a tone, 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 B locrian 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 B locrian is spelled the way it is, rather than with whichever accidental looks tidier.

Every letter already falls where the pattern needs it, so B locrian is written with no sharps or flats at all.

The B locrian scale needs no sharps or flats, because every letter already falls where the S T T S T T T pattern of steps needs it.

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 B locrian scale has seven playable positions, at frets 2–6, 3–7, 5–9, 7–11, 9–13, 10–14 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

The climb runs from fret 8 to fret 17 and plays 21 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.
