B♭ Major Pentatonic Scale in Practice

The B♭ Major Pentatonic Scale uses the key signature of 2 flats (B♭, E♭). Bb major has two flats (Bb, Eb) and is extremely common in jazz and wind ensemble music. It is the home key for Bb instruments such as the trumpet and tenor saxophone. On guitar, B♭ positions offer comfortable transposing instrument keys for this scale.

The major pentatonic scale uses five notes from the major scale, omitting the 4th and 7th degrees. It has a bright, open sound widely used in folk, country, and pop music. When played starting on B♭, the 5 notes are B♭, C, D, F, G. In this key the signature has 2 flats (B♭, E♭). Bb is the concert-pitch key when Bb instruments (trumpet, clarinet, tenor sax) play in their native C, making it the most common jazz and band key. Jazz standards in Bb are ubiquitous — tunes like "Autumn Leaves" and "All Blues" sit naturally for horn sections, and the key is a default for jam sessions.
