I wish these dozen videos from Lulie Landsman had been around a few decades ago. When I first began using the method, I had help from my teacher, but he had never studied with Caruso, Laurie Frick, or Julie Landsman, so much of the nuance of the method was inaccessible.
If you’re a brass player, give these a try. In addition, check out the practice calendar and the sheet music PDFs Ms. Landsman has provided. There’s a bunch of her printable resources here, but be aware the video links are dead, hence the videos below.
