The low B ♯ (played in the seventh position on the large F bass trombone), is missing on the B ♭ /F combination. Unfortunately, the standard length B ♭ slide is not quite long enough to accommodate a true low C 2 (with the attachment actuated), although professional players compensate for this deficiency by embouchure adjustment. Accordingly, it is now quite common for B ♭ trombones to include an F attachment. Thus, it was logical to combine the two traditional B ♭ and F instruments into a single design by adding an F attachment to the standard B ♭ trombone. At the time of the invention of this thumb-actuated valve, a nominal trombone section consisted of an alto in E ♭, a tenor in B ♭, and a bass in F (i.e., a grouping in perfect fourths). In 1839, a thumb-actuated valve was invented by Sattler, in Leipsig. Prior to 1839, the tone sounded by trombones was generally achieved by changing the embouchure and the slide position. Extending the tube length of the instrument by a slide rather than by valves, permits a continuous, rather than discrete change in pitch, which provides a sound unique to the trombone as compared to other wind instruments. Lubricant is applied to the stockings before the instrument is played and permits the slide to ride freely along the inner tube members by varying the length of the tubing through which air travels between the mouthpiece and the bell of the trombone. The slide is slidably mounted on the two fixed-length straight tube members by slipping the slide legs over the inner tube stockings. A U-shaped section of tubing forming a "slide" provides two leg portions, each having an inner diameter slightly greater than the outer diameter of the stockings of the fixed length straight members of the tubing. The free end of each of the fixed lengths of tubing, or receivers, terminates in a raised angular section or lip called a stocking. A second fixed length of straight tubing is coupled on one end through a U-shaped section of tubing to the bell. The trombone also includes a bell from which the sound emanates when the instrument is played. The conventional trombone has a mouthpiece mounted on a fixed length of straight tubing. Generally, a slide trombone player will vary the length of tube and the resulting sound pitch by selectively telescoping the trombone slide relative to the bell portion of the trombone. The slide trombone is a brass wind instrument which relies on varying the length of tubing through which air passes to vary the pitch of the resulting sound. More particularly, the trombone has two independently operated trigger attachments wherein a thumb trigger operates an attachment lowering the windpath by a minor third and a finger trigger operates a second attachment lowering the windpath by approximately a tritone so that the two attachments together lower the windpath by a total of a minor sixth. The present invention relates to trombones, and more particularly to a slide trombone having an in-line double attachment which achieves better technical facility and a complete chromatic range. Said slide trombone having a first attachment activatable by a thumb trigger and a second attachment activatable by a finger attachment, an activatable attachment which lengthens the basic windpath to define a lengthened windpath when activated, said slide assembly including a slide which is positionable to lower the pitch of the basic windpath when said attachment is activated whereby the basic windpath is tuned to B ♭, the first attachment is tuned to G, the second attachment is tuned to E, and the two attachments together are tuned to D.

Said slide trombone having a first activatable attachment and a second activatable attachment each of which independently and together lengthens the basic windpath to define a lengthened windpath when activated, said slide assembly including a slide which is positionable to lower the pitch of the basic windpath when said attachment is activated whereby the first attachment lengthens the windpath and lowers the pitch of the basic windpath by a minor third, the second attachment independently lengthens the windpath and lowers the pitch by approximately six semitones of the basic windpath, and the first and second attachment together lengthen the windpath to lower the pitch of the basic windpath by a minor sixth.Ģ.
