Each of the AB pieces is just a minute or two long. Listen to the set and then choose one you feel like having a go at. Listen carefully to the song and when you’re ready, scat-sing with it (without making the neighbours question your mental health!) – that’s a good way to embed the tune in your musical brain...like ’ ba dad’n dad’n dad’n dadat!’ for the opening bass line on Miles’ ‘So What’ from ‘Kind of Blue’, for example. Then when you’re ready, join in on your instrument, ‘shadowing’ or imitating any bits you can, like this bass line, you’ll soon get the hang of it. Break the song into small chunks that you find manageable and try carefully to play them one by one. Backtrack on the recording as many times as necessary to get the tune right, and pause it to crunch slowly through phrases that trip you up. Don’t worry about speed, that will come with practice. You’ll progress from being able to play just a few notes to some key phrases to the whole piece, by matching what you hear with what you’re doing on your instrument, reinforced by what you’re able to make sense of from the chart, but be prepared to give sustained attention to just one song.
