Tune up systems

This is just a preliminary review of a new program that I got. I am always seeking ways to better my trombone playing and this looked very good. I had met someone who used it over the summer. His intonation had improved a small amount. It is called tuneup systems and teaches you how to play in tune. It took me about two weeks to receive it after I ordered it. This made me a little nervous. I paid about sixty dollars for it and I was afraid that my package had been lost. When I got the package it came with two discs. One was a PDF file of about sixty pages and the other one was an audio cd. The PDF goes into detail on how to use the discs and about intonation. It shows the mathematics behind intonation. After a brief technical overview it goes into exercises. To do the exercises you put on the specified track on the cd and hum or play. Humming is a huge part of it. It somehow gets you to really hear the pitch. You can feel it in your sinus cavities when you do it right. I will put up further posts as I get farther along
