Review the most problematic keys/scales/arpeggios from the past week today. Ideally, every scale is (almost) equal in facility.
Go through all if you can, but spend the most time on the least familiar material. This is to make up for the flaw in this one-key-per-day method: it’s all very neat and organized, but our knowledge of keys is not the same for every key. So spend some time now to help F# and Ab etc. catch up to C.
Make sure you treat yourself and jam on the least familiar material as well. The best-kept secret in horn technique is that the best way to acquire technique is to jam on any particular technique, getting to know it in as many ways as you can, forwards, backwards, upside down, jumbled, and so on. It’s also a lot of fun!
