Abstract: A brass wind instrument which changes pitch by varying the tube lengths thereof which includes a slide portion which is substantially half the physical length of a conventional slide. The slide assembly comprises two substantially U-shaped tubes which slidably engage corresponding tubes on a fixed portion of the trombone. The fixed portion of the trombone accommodates a conventional bell and a conventional mouthpiece. The slide assembly includes first and second substantially U-shaped slide tube members each having a pair of adjacent legs that slidably engage the fixed portion of the trombone. The slide assembly is configured such that customary pitch positions are obtainable.

Abstract: A brass wind instrument incorporating a compact slide configuration comprising two U-shaped slide tube members, each having two tube lengths which are proximate to each other and which are coupled together with a minimum length crook. The two U-shaped slide tube members, in the preferred embodiment, are in parallel planes and are permitted to reciprocate, during use, on four corresponding fixed length receiver tube members.

Abstract: A musical instrument case for wind instruments providing a body having an instrument storage chamber formed therein. The instrument is placed into the storage chamber through a mouth, a lid being provided to cover the mouth and at the same time to be inserted into the bell of the instrument to secure the same in position. A storage chamber can be provided in the lid and the body is tapered to conform on the inside thereof as well as on the exterior thereof substantially to the shape of the instrument to be stored.
