On the staff

BCDEF♯GAB

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

This is one octave of the B phrygian 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 T S 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 phrygian 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 phrygian 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 B, one letter cannot keep up:

  • F♯ — the fifth. The pattern needs a tone from E, but E to F is only a semitone, so F has to rise to F♯.

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 B phrygian scale is written with F♯, because the S T T T S T T pattern of steps cannot be spelled with plain letters from B.

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 seven notes as a shape you can see. The coloured keys are the B phrygian scale, and you can click any key to hear it.

The B phrygian scale has seven playable positions, at frets 2–6, 4–8, 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 9 to fret 21 and plays 22 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.
