I haven’t yet watched all videos and gone through all the PDF downloads, but if the quality is consistent from the first video this is a great series of instructional videos for brass players wanting to learn more about the pedagogy of Carmine Caruso. Here’s the first video.
Landsman has been the principle horn player for the Metropolitan Opera for over 25 years and is on the faculty of The Juilliard School.
You can go here to see all the videos embedded and go here to download the printable PDF files that included written instructions and sheet music for horn. If you play another brass instrument you’ll need to adopt and transpose some of the exercises, but it should be pretty easy for anyone to work out how to do that.
