Paul The Trombonist here, these videos are a series of private trombone training videos that one of my students previously paid 1,000's of dollars for when he commissioned me to make them for him.
He went through my method book and youtube videos and was looking to get more insight.
These videos helped him so much that he reached out to me to tell me that they should be made public.
Not too long ago, we made them public over a weekend, many people enrolled into the program, and then we closed access.
The results we got back were so good, that the decision was made to open access again one more time.
Since Trombone Secrets has started it has evolved into a living breathing resource of trombone lessons!
