This play along jam track has a 4 bar intro by the double bass, which follows the roots of the 7th and 6th degree (from Ab major to Gb major) of Bb minor and lands on the dominant F7 chord (F, A, C, Eb). Start playing the diminished arpeggio exercise together with the bass run and you will be able to play the entire piece as demonstrated in the video. The notation at the top of the page is taken from the Jamtracks PDF showing the notes of the double bass. Although the diminished guitar arpeggio (A, C, Eb) does not contain the root of F7, all further intervals of the chord (A, C, Eb) are played in the exercise. Fill the outro afterwards by improvising freely with the diminished arpeggio until the end.
