I really enjoy playing Christmas music and over the years have learned several songs from Jingle Jazz by Phillip Keveren, from Hal Leonard. This book is filled with Christmas music with a variety of jazz, swing and Latin styles, that are great to teach and learn personally. Phillip Keveren took great care in deciding the jazz styles of many Christmas songs, including Caroling Caroling, Rudolf the Red-Nosed Reindeer, Jingle Bells and many more. Wanted to share three YouTubes from the book. If you don't have a copy, considering get this late intermediate book for yourself or to teach to your students. Thanks for your support. Blessings.
