Richie Powell is one of my favorite hard bop pianists. His vocabulary is clear and accessible and this solo is a great example of that. He died at a young age in the same accident that took the life of his contemporary (and bandleader on this album) Clifford Brown.
Listen for the inventive rhythmic variety that helps the blues scale come to life and the way the energy builds over the three choruses, resolving gracefully in the lower octave.
This app comes very close to the vision I had three years ago of being able to jot down by hand a quick melody on my iPhone or iPad and immediately be able to hear back the notes or copy them into a music engraving program like Finale or Sibelius (or Notion on the iPad).
While the recognition is not perfect, I have high hopes for this type of workflow in the future.
As for the music, if you have ever wondered how to use the blues scale effectively, check out Richie’s three choruses on Sandu. Only once or twice does he play a note outside the blues scale, but he finds a way to sound fresh on each chorus and build the intensity thought the entire solo. This would be a good first transcription for a beginning improviser.
