I love Telemann, and was thrilled when I found these Canonic Sonatas. These are not too hard, but still challenging. The sonatas would sound very nice in a church service. Good for teachers to play with their students or for two trumpets who just want to get together and play some great music. The online midi file is also fun/helpful to play along with if you can't find another trumpeter. All six Sonatas are tons of fun.
