So I'm finally getting off my butt and auditioning for one of the Cornell Jazz Ensembles. I'm going for a small group because my reading (highly necessary for big band, obviously) is somewhere between "ass" and "go back to Tabcrawler." Simple enough--all I have to do is walk a couple choruses of "What Is This Thing Called Love?" and solo over a chorus. What's tricky about this chart is that the director has the A sections in a bossa feel, but the B in conventional swing. Going between bossa and swing is tricky. Any tips from the resident jazzoids as to how to make this transition somewhat smoother? My solos are sounding like ASS.
