This is a great resource for any musician to have. I recently played at a synagogue for a food festival, and I put together a small jazz group to play some songs out of this book. It is nice that it has chords and words, and enabled us to play with a jazz combo. The only suggestion I would have for this book would be to detail what specific holiday, occasion, or festival each song belongs to, so that someone doesn't play a funeral song at a birthday or something!Otherwise, this book is laid out very well and very easy to use.
