Harmony

The chromatic scale contains all 12 pitch classes and has no diatonic harmony — all chromatic passages use all pitches equally. See individual chord types for specific harmonic structures.

Key Signature

5 — The B key signature uses F♯, C♯, G♯, D♯, A♯.

B Chromatic Scale in Practice

The B Chromatic Scale uses the key signature of 5 sharps (F♯, C♯, G♯, D♯, A♯). B major has five sharps and a bright, somewhat tense quality. Enharmonically equivalent to Cb major, it is used in orchestral writing and some jazz compositions. On guitar, B positions offer open-string resonance for fingering positions for this scale.

The chromatic scale includes all 12 pitches within an octave, each a half step apart. It has no tonal center and is used as a reference for all other scales and as a compositional device. When played starting on B, the 12 notes are B, C, C♯, D, D♯, E, F, F♯, G, G♯, A, A♯. In this key the signature has 5 sharps (F♯, C♯, G♯, D♯, A♯). B sits at the boundary of comfortable sharp keys with 5 sharps, often used in orchestral writing for brilliance and in jazz for challenging ii-V-I exercises. Guitarists can play in B using barre chords at the second and seventh frets, and the key is common in pop and R&B music when vocalists prefer its tessitura.

Guitar: B Chromatic Scale Positions

The B key offers 5 sharps (F♯, C♯, G♯, D♯, A♯) on guitar. Sharp-side keys like B are idiomatic guitar keys because open strings (E, A, D, G, B, E) align with the scale's natural resonance points.
