In the Australian state of Victoria, the Victorian Curriculum and Assessment Authority has set out minimum standards for its electric bass students doing their end-of-year Solo performance recital. To graduate, students must perform pieces and songs from a set list that includes Baroque suite movements that were originally written for cello, 1960s Motown tunes, 1970s fusion jazz solos, and 1980s slap bass tunes. A typical program may include a Prelude by J.S. Bach; "Portrait of Tracy" by Jaco Pastorius; "Twisted" by Wardell Gray and Annie Ross; "What's Going On" by James Jamerson; and the funky Disco hit "Le Freak" by Chic.
Most basses have a volume potentiometer ("pot" or "knob"), which can be turned up or down, and a tone potentiometer, which rolls off the high frequencies when it is turned to the player's right. Some basses may also have a pickup selector control or switch, to select single-coil or humbucking pickups. Since the 1980s, basses are often available with battery-powered "active" electronics that boost the signal with a preamplifier and provide equalization controls to boost or cut bass and treble frequencies, or both. Some expensive basses have even more equalization options, such as bass, middle and treble.
Traditional digital pianos vaguely resemble an electronic organ or a spinet harpsichord but usually lacking a fully enclosed lower section, while some models are based on the casework of traditional upright pianos with a fully enclosed bottom part and pedals that look like actual piano pedals. An opposite and recent trend is to produce an instrument which has a unique and distinctive appearance, unobtainable with a conventional instrument. Yamaha , Kawai and Casio makes a model which is designed to stand against a wall and is far shallower from keyboard to back than any possible upright design, as well as shorter height.
While fretless basses are often associated with jazz and jazz fusion, bassists from other genres have used fretless basses, such as Freebo (country), Rick Danko (rock/blues), Rod Clements (folk), Steve DiGiorgio, Jeroen Paul Thesseling (metal), Tony Franklin (rock), and Colin Edwin (modern/progressive rock). Some bassists alternate between fretted and fretless basses in performances, according to the type of material or tunes they are performing, e.g., Pino Palladino or Tony Levin.
Yet another form is the portable digital piano which is what appear to be combining the capabilities of stage pianos, but with additional features similar to a conventional digital keyboard. These digital pianos are mostly designed for various purposes such as home, studio, classroom, stage or personal use. It is similar in form to a stage piano, but much lighter in weight, and having a more compact size. Unlike stage pianos, portable digital pianos were commonly equipped with built-in amplification and loudspeakers, usually has lower cost than other types, and its sound quality were often comparable or similar to that of a regular digital keyboards due to a simpler sound synthesis system, though some models, still utilize a similar sound engine as the more advanced model lineups of the same manufacturer.
A pick (or plectrum) produces a more pronounced attack, for speed, or personal preference. Bass with a pick is primarily associated with rock and punk rock, but player in other styles also use them. Jazz bassist Steve Swallow often plays with a pick, while Pink Floyd bassist Roger Waters uses one for a heavier tone. Mike Gordon of Phish uses a pick while also incorporating slapping techniques into his playing. Picks can be used with alternating downstrokes and upstrokes, or with all downstrokes for a more consistent attack. The pick is usually held with the index and thumb, with the up-and-down plucking motion supplied by the wrist.
