I found it when looking at a trumpet page online. Has anyone tried it? We all know that Cat Anderson could play triple A's and B's, but is his method worth playing through. For those who aren't familiar, each lesson (each one is played for 2-5 days) starts out with a ppp middle staff g long tone for 20 minutes followed by 10 minutes of rest and then goes on to a middle c for 20 minutes, only with a crescendo. After this there are some range exercises on each page.
