These are plain .GIF files, originally created using Microsoft Excel spreadsheets. The number of beats on each degree of the diatonic scale was entered and totaled to create the chart. Originally I was intending to write one for each song, but although they were an intriguing and worthwhile exercise in coming to know these songs intimately, they are extremely time-consuming to write. Since realistically I can't expect them to be of major use to performers, especially without the scores, I have left off writing them. I provide those I have written for those few who may be interested.
Additional suggestions are welcome.
