On modern band and orchestral drums, the drumhead is placed over the opening of the drum, which in turn is held onto the shell by a "counterhoop" (or "rim"), which is then held by means of a number of tuning screws called "tension rods" that screw into lugs placed evenly around the circumference. The head's tension can be adjusted by loosening or tightening the rods. Many such drums have six to ten tension rods. The sound of a drum depends on many variables—including shape, shell size and thickness, shell materials, counterhoop material, drumhead material, drumhead tension, drum position, location, and striking velocity and angle.
Another common form is the stage piano, designed for use with live performances, professional audio, or in recording studio. This type of digital piano normally makes no attempt to imitate the physical appearance of an acoustic piano, rather resembling a generic synthesizer or music workstation. A distinguishing feature of most stage pianos is a lack of internal loudspeakers and amplification - it is normally assumed that a powerful keyboard amplifier or PA system will be used. However, some stage pianos are equipped with powered speakers.
A three-piece drum set is the most basic set. A conventional three-piece kit consists of a bass drum, a 14" diameter snare drum, 12"–14" hi-hats, a single 12" diameter hanging tom, 8"–9" in depth, and a suspended cymbal, in the range of 14"–18", both mounted on the bass drum. These kits were common in the 1950s and 1960s and are still used in the 2010s in small acoustic dance bands. It is a common configuration for kits sold through mail order, and, with smaller sized drums and cymbals, for kits for children.
