"What'll I Do" is a beautiful composition by Irving Berlin. In this four-page arrangement, the verse, an intro, the melody, an improvised solo section, and an ending are included. All dampening and pedaling is notated, along with chord symbols and voicings.
 
This can be an effective standalone piece for a classical musician, or an inspired jumping-off point for the serious improviser. Feel free to write to me at olivermaymanmusic@gmail.com with any questions about the arrangement.
