Thank you very much for viewing. This is the trombone method book "Lip Slurs" (Brad Edwards). It's a lip slur etude by Edwards, a trombone player and well-known instructor. The content consists of three parts: "Slow Slurs," "Fast Slurs," and "Melodies using Lip Slurs." The difficulty is designed to increase gradually, making it a popular and comprehensive method book. I purchased and used this about 10 years ago, so there are some pencil markings. I've erased them with an eraser, but there are some areas where traces remain. The staples inside have also rusted, but I think the overall condition is good. Please, give it a try. Please understand that this is a used item and consider accordingly.
