Jamey Aebersold Jazz, Volume 42: Blues in All Keys: Book & Online Audio

This volume cuts through the overwhelming nature of learning blues in all twelve keys by pairing each transposition with a unique melody and compatible harmonic framework. The slow tempos mean students at intermediate and advanced levels can build genuine fluency across keys without feeling rushed, and the rhythm section (Williams, Cranshaw, Roker) plays with the kind of musical maturity that pulls soloists toward better phrasing and time feel.

You're sitting in a real jazz combo, working through blues changes that shift with each tune. The rhythm section is locked and patient, never rushing you through the uncomfortable keys. Each new transposition feels like a small challenge your ear rises to meet.

Intermediate and advanced jazz students who can solo over blues changes but haven't yet developed equal fluency across all keys. This also serves musicians preparing for jazz ensemble auditions or competitions where transposition is expected.

• Play the first few keys looking at the music to lock in the melody and changes, then return to earlier keys and try improvising without the page. This builds ear training faster than running through all twelve keys by sight.
• Record yourself soloing over each key for two or three choruses, then listen back. You'll hear exactly where your phrasing tightens up in unfamiliar keys and where you're already comfortable.
• Focus on the chord-scale progressions provided rather than memorizing lick patterns. Understanding how the changes move in each key transfers across all twelve.
• Revisit the tougher keys (B, F-sharp, D-flat) multiple times across several practice sessions rather than cramming them in one sitting. Your ear needs time to recalibrate to new tonalities.

Use this as a guided independent study resource for jazz ensemble members who need systematic key-study work outside of full-group rehearsal. Alternatively, dedicate one week of ensemble rehearsal to working through a single key together, with the whole band soloing and learning how the melody sits in that transposition before breaking into sectional practice.

• Blues improvisation in all twelve keys
• Chord-scale relationships across transpositions
• Ear training through solo transcription and playback
• Phrase development over extended blues choruses
• Time feel and rhythm section interaction
