Bb Major Pentatonic Scale
The Bb major pentatonic scale (also written A#) — Bb C D F G — with its intervals, the chords it makes and every position on the guitar neck.

Chords to play Bb major pentatonic over
Bb major pentatonic is the major scale with the 4 and the 7 left out — the notes most likely to clash — so it works across the chords of Bb major. It is not an equally good fit on every one of them: over each chord, aim for that chord’s own notes and let the rest pass.
How to practice the Bb major pentatonic scale
- Start with position 4 at frets 0–3, slowly, until every note lands on the click. The loop keeps the shape and the tempo for you.
- Add five beats a minute each time it feels easy. When straight runs get dull, play the same position in thirds — the pattern that turns a scale into lines.
- See every Bb major pentatonic note across the whole neck on the Fretboard, and find each box again an octave up.
