The snare drum is the heart of the drum kit, particularly in rock, due its utility of providing the backbeat. When applied in this fashion, it supplies strong regular accents, played by the left hand (if right handed), and the backbone for many fills. Its distinctive sound can be attributed to the bed of stiff snare wires held under tension to the underside of the lower drum head. When the stiff wire are "engaged" (held under tension), they vibrate with the top (snare-side) drum skin (head), creating a snappy, staccato buzzing sound, along with the sound of the stick striking the batter head.
The fretting hand—the left hand for right-handed bass players and right hand for left-handed bass players—presses down the strings to play different notes and shape the tone or timbre of a plucked or picked note. One fretting technique is a finger per fret, where each finger in the fretting hand plays one fret in a given position, giving the advantage that full chromatic scale of over an octave and a half can be played with no up-down wrist movement. Also, the double bass-style technique can be used for fretting. This technique involves using four fingers in the space of three frets, especially in the lower positions (i.e., the fretting positions closer to the nut, where the space between notes is the widest). When considering the spacing between notes, this is a comfortable distance for the average person's hand size, however it requires more up-down hand movements. The main advantage of the "four fingers in three frets technique is less tendon strain, leading to a diminished likelihood of Repetitive Strain Injury (RSI). The image below (of a bassist performing tapping) shows the four-in-three.
I brought in several other pianists for our test panel. Liz Kinnon is a pianist/arranger/composer/educator from Los Angeles who has performed with artists such as Dizzy Gillespie and Andy Williams. She was an orchestrator on the animated shows Animaniacs, Pinky and the Brain, and Histeria. At the Colburn Community School of Performing Arts in Los Angeles, she teaches jazz piano and is the Director of Adult Jazz Combos. She was Ryan Gosling’s piano coach for La La Land and recently worked with Simon Pegg and Juno Temple for the film Lost Transmissions.
Microphones ("mics") are used with drums to pick up the sound of the drums and cymbals for a sound recording and/or to pick up the sound of the drum kit so that it can be amplified through a PA system or sound reinforcement system. While most drummers use microphones and amplification in live shows in the 2010s, so that the sound engineer can adjust and balance the levels of the drums and cymbals, some bands that play in quieter genres of music and that play in small venues such as coffeehouses play acoustically, without mics or PA amplification. Small jazz groups such as jazz quartets or organ trios that are playing in a small bar will often just use acoustic drums. Of course if the same small jazz groups play on the mainstage of a big jazz festival, the drums will be mic'ed so that they can be adjusted in the sound system mix. A middle-ground approach is used by some bands that play in small venues; they do not mic every drum and cymbal, but rather mic only the instruments that the sound engineer wants to be able to control in the mix, such as the bass drum and the snare.
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.
