On the staff

B♭CD♭E♭FG♭A♭B♭

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

This is one octave of the B♭ natural minor 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 S T T S T T: a tone, a semitone, 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♭ natural minor 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♭ natural minor 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♭, four letters cannot keep up:

  • D♭ — the flat third. The pattern needs a semitone from C, but C to D is only a tone, so D has to fall to D♭.
  • E♭ — the fourth. The pattern needs a tone from D♭, but D♭ to E is only a tone and a half, so E has to fall to E♭.
  • G♭ — the flat sixth. The pattern needs a semitone from F, but F to G is only a tone, so G has to fall to G♭.
  • A♭ — the flat seventh. The pattern needs a tone from G♭, but G♭ to A is only a tone and a half, so A has to fall to A♭.

None of those accidentals was 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♭ natural minor scale is written with B♭, D♭, E♭, G♭ and A♭. B♭ has its accidental because that is the key, and the other notes need theirs because the T S T T S T T pattern of steps cannot be spelled from B♭ with plain letters.

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♭ natural minor scale has seven playable positions, at frets 1–5, 2–6, 4–8, 6–10, 7–11, 9–13 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 11 to fret 23 and plays 25 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.
