The trombone produces notes within its range by extending the main slide to different positions. In first position, the length of the bore is at its shortest; seventh position puts the slide at its furthest extension, at the edge of the inner slide's stockings. (These are sections of slightly greater diameter at the ends of the inner slide tubes.)
The note E 1 (or the lowest E on a standard 88-key piano keyboard) is the lowest attainable note on a 9-foot (2.7 m) B♭ tenor trombone, requiring a full 7 feet 4 inches (2.24 m) of tubing. On trombones without an F attachment, there is a gap between B♭ 1 (the fundamental in first position) and E 2 (the first harmonic in seventh position).
Non-compensating instruments and trombones must not use the third position or valve combination because it is not in tune; other combinations must be altered drastically. Some musicians prefer to extend the tablature numbering system to 12 or more; others prefer a symbol to indicate a lesser-used, longer valve.
The B ♭ valve makes alternative slide positions available for notes in longer positions, and allows the range above the pedals to extend from A 2 down to F 2. Many manufacturers offer an alto model in their trombone range, including Yamaha , Bach , Conn , SE Shires, Thein, Rath , and others.
Notes below B ♭ are called for only rarely as they "become increasingly difficult to produce and insecure in quality" with A ♭ 1 or G1 being the bottom limit for most trombonists. [1] Pedal tones are called for occasionally in advanced brass repertoire, particularly in that of the trombone and especially the bass trombone.
Brass instruments originally had no valves, and could only play the notes in the natural overtone, or harmonic series. [14] Brass instruments still rely heavily on the overtone series to produce notes: the tuba typically has 3-4 valves, the tenor trombone has 7 slide positions, the trumpet has 3 valves, and the French horn typically has 4 ...

For example, the trombone is played with a slide, making it one of the few wind instruments capable of glissando or sliding. However, pitches are different harmonics from the harmonic series on different slide positions. Thus, in the lower range, significant movement of the slide is required between positions, but for higher notes the player ...
