Here is a link to my transcription of Lennie Tristano's right hand on "Note To Note," recorded in 1964 or 1965. The chord changes, as Tristano lets on melodically in the first three measures, are those of Jerome Kern's "All The Things You Are."
While a transcription of Tristano's left hand would be illuminating, his harmonic substitutions are mostly apparent in the construction of the melodic line. His sophisticated and idiosyncratic rhythmic sense is also demonstrated to great effect.
As always with the transcription of jazz improvisations, "Caveat auditor."
