One of my students recently brought to my attention what appears to be a brand new edition of the Arban Book for trumpet. It’s published by Dover, and Amazon.com is currently taking preorders at $14.95. That’s the lowest price I’ve seen on this book in more than 20 years.
A lot of people call this book the “bible” of trumpet. I’m not sure I’d go quite that far, but it is a great tool for mastering the instrument. This might be a great opportunity to pick one up!
