The clever title says it all: this is a great introduction to B flat “rhythm” changes. Swinging throughout at a tempo of 132 every section of the band gets a chance to shine. There are three written solos…Alto Sax 1 on the first “A” section, Trumpet 1 or 2 on the second “A” and Piano on the bridge. A fun shout chorus leads to a recap of the catchy tune with a splashy Basie ending.
