Why the C major pentatonic scale has no sharps or flats

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 C 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 C major with some notes taken out, and it keeps that scale's spelling exactly.

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

The C major pentatonic scale needs no sharps or flats, because every letter already falls where the T T T+S T T+S 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 C major pentatonic scale has five playable positions, at frets 0–3, 2–5, 5–8, 7–10 and 9–13.

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 1 to fret 14 and plays fifteen 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.
