This is a tune I wrote for Allan Holdsworth right after he passed away in 2017. It is based entirely on "The Diminished Scale" or "Messiaen's 2nd Mode." There are no chord symbols because I wasn't thinking of any particular root or voicings; I tried to base the voicings on notes within the scale. You can think of anything contained in this tune as being related to E7b9, G7b9, Ab7b9, Bb7b9, or Abdim7, Bdim7, Ddim7, or Fdim7. I hope you get something out of it. Enjoy!
