All the music from the Intermediate Band folder can be found here, along with practice recordings to play along with.
You should do a warm up, consisting of a few exercises from the band warmup sheet. Then work on a combination of solo songs, either from the taskbook list or the “fun songs to play” sheet, and band music.
If you lose your folder, email rwpsband@gmail.com and you can request the pdfs so you can print out a replacement yourself.
