B Phrygian Mode in Practice

The B Phrygian Mode 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 Phrygian mode has a dark, exotic quality due to its flat 2nd degree. It is characteristic of Spanish flamenco music and heavy metal, creating an intense, mysterious atmosphere. When played starting on B, the 7 notes are B, C, D, E, F♯, G, 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.
