This book aims to help beginners play the trombone. Like all brass instruments, the trombone changes pitch when the physical length of the tubing the air passes through changes. The trombone has a special extendable slide that functions as the valves do on other brass instruments. The trombone changes length when the player extends the main slide. When the slide gets longer, the pitch goes lower.
The book includes 32 trombone diagrams with fingering positions, along with pitch names and staff notations. Each note here has its own page in the book. The musical notes in this book cover almost 3 octaves from E2 to B4.
The trombone's slide has seven positions: the 1st position is when the slide is pulled closest to you and the 7th is when it is fully extended. However, the slide has no markers indicating these positions. On each page, the slide position in red corresponds to the particular note depicted. When there are two red numbers for the same note, it means that there are two variations for the slide position to create that note.
