Songs Of Thankfulness and Praise, Sleepers Wake and How Brightly Shines The Morning Star are just three of more than 300 chorales that J. S. Bach harmonized. These are great pieces for warm-ups (each chorale is in a different key: D, G and C as well as concerts. Excellent for teaching balance, blend, intonation, musical style, phrasing, and attacks and releases. This will add great dignity to your next concert!
