Here's a superb arrangement for vocal solo and jazz ensemble in two keys by Dave Wolpe. The parts are reversible -- just flip the page for the key that suits your vocalist. A brief trumpet solo and some tenor sax lead a la the "Four Brothers" sound plus all the usual Wolpe flair make this chart a winner. The low key (female) is A-flat with a range from G below middle C to third line B. The high key (male) in pitched in C with a range from B below middle C to fourth space E-flat. (2:34)
