“Hora Decubitus” (a.k.a.”E’s Flat Ah’s Flat Too”) comes from my favorite Charles Mingus record, Mingus Mingus Mingus Mingus Mingus from 1963. The tune is a E-flat minor blues with a harmonic twist. Each chorus of the melody adds a new layer of counterpoint. I love to teach this tune by ear in my large group improvisation workshops. Below is my transcription of the horn parts. Enjoy!
