My idea is to do the following:
Sept: Recorder, basics, reading, etc...
Oct-Dec: Students learn instrument #1. I hope to have trumpets, clarinets, and flutes. They will perform on this instrument at the winter concert.
January-Feb: Rotate instrument. Student learns new instrument, but hopefully this moves faster since they can read at this point.
March: Student learns third instrument.
April-June: Student is assigned (or student chooses) their best instrument. Performs with full band at Spring Concert.
Now, we only have 8-10 kids in the regular band. So getting this right is a huge deal.
