Here’s a transcription of Ray Brown’s walking on his tune “Bass Face” performed live with his trio in 1993 at Jazz Umbria, with Benny Green and Jeff Hamilton. I didn’t include chord changes because they throw in so many substitutions, it’s best to hear the line in context by playing along with the recording. It’s rhythm changes in C, with a different bridge from the typical rhythm changes bridge.

Here’s a James Jamerson transcription, being played on my 1969 Fender Precision Bass.
