The word "transcription" means here the process (or the result) of listening to a piece of music and writing down the score by ear.
Here are some accurate scores for various instruments: guitar (+ TAB), piano, winds and jazz orchestra.
This collection includes works by great artists such as Pat Metheny, Chris Potter, Bob Mintzer, Scott Henderson, Dave Holland, Guthrie Govan and it is increased every now and then in the free time.
Some of the transcriptions are coloured to highlight chord substitutions or superimpositions making easier to see in real time what the soloist is playing from the harmonic point of view.
