I have finally located another source for the Gatti Method. The Carl Fischer edition was what I used with Claude Gordon in the 1980s and 1990s, which was a translated edition of the original. This is the original in three volumes. I am currently using this will all of my students and myself. The Gatti Method is an essential item for any brass player's library. My favorite section of the book is where it has a scale study with models, an etude and a duet in each major and minor key. The duets are fun, operatic, and in the style of cornet solos of the past.
The online store is being renovated. In the meantime all the items pictured in these slides are available for purchase. Use the contact form on this site to email what you want to purchase and I will send a PayPal invoice for the books and postage. Also, include your mailing address and other contact information to speed up the process.
Thank you for your business and patience!
