Romantic songs always communicate well with the audience, and this Gershwin¨ classic is one of the best. This flexible arrangement is written in two keys by creative arranger Dave Wolpe. The higher key is designed for a male vocalist and the lower key for your female vocalist, and the parts are printed back to back -- just flip the page. Low (female) key of C range is G below middle C to third line B. High (male) key (F) range is middle C to fourth space E. This is a must-have vocal solo with jazz ensemble -- superb!
