On a treble staff, the B♭ major pentatonic scale is written B♭ C D F G.

The solid notes are the B♭ major pentatonic scale. The pale notes are the rest of B♭ major, the larger scale it is carved out of, so you can see which notes it leaves out.

A scale is a pattern of steps, and this one is T T T+S T T+S: a tone, a tone, 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. The pattern is what gives B♭ major pentatonic its sound, and it stays the same whichever note you start on.

This scale has only five notes, so it does not use every letter. It is B♭ major with some notes taken out, and it keeps that scale's spelling exactly.

Apart from the tonic, no note needs a sharp or a flat, because every other letter already falls where the pattern needs it.

The B♭ major pentatonic scale is written with B♭. Only the tonic carries an accidental, and that comes from the key you picked rather than from the T T T+S T T+S pattern of steps.

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♭ major pentatonic scale has five playable positions, at frets 5–10, 7–12, 10–15, 12–17 and 15–20.

There are five shapes, and each one starts on a different note of the scale. Once you know one shape you can slide it along the neck, and once you know all five they join up to cover the whole neck.

One climb up the neck

The climb runs from fret 8 to fret 22 and plays eighteen 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 three notes on every string. The widest stretch on any one string is five frets.
