The fretting hand can add vibrato to a plucked or picked note, either a gentle, narrow vibrato or a more exaggerated, wide vibrato with bigger pitch variations. For fretted basses, vibrato is always an alternation between the pitch of the note and a slightly higher pitch. For fretless basses, the player can use this style of vibrato, or they can alternate between the note and a slightly lower pitch, as is done with the double bass and on other unfretted stringed instruments. While vibrato is mostly done on "stopped" notes—that is, notes that are pressed down on the fingerboard—open strings can also be vibratoed by pressing down on the string behind the nut. As well, the fretting hand can be used to "bend" a plucked or picked note up in pitch, by pushing or pulling the string so that the note sounds at a higher pitch. To create the opposite effect, a "bend down", the string is pushed to a higher pitch before being plucked or picked and then allowed to fall to the lower, regular pitch after it is sounded. Though rare, some bassists may use a tremolo bar-equipped bass to produce the same effect.
If a second hanging tom is used, it is 10" diameter and 8" deep for fusion, or 13" diameter and one inch deeper than the 12" diameter tom. Otherwise, a 14" diameter hanging tom is added to the 12", both being 8" deep. In any case, both toms are most often mounted on the bass drum with the smaller of the two next to the hi-hats (on the left for a right-handed drummer). These kits are particularly useful for smaller venues where space is limited, such as coffeehouses and small pubs.
Drummers use a drum key for tuning their drums and adjusting some drum hardware. Besides the basic type of drum key (a T-handled wrench) there are various tuning wrenches and tools. Basic drum keys are divided in three types which allows tuning of three types of tuning screws on drums: square (most used), slotted and hexagonal. Ratchet-type wrenches allow high-tension drums to be tuned easily. Spin keys (utilizing a ball joint) allow rapid head changing. Torque-wrench type keys are available, graphically revealing the torque at each lug. Also, tension gauges, or meters, which are set on the head, aid drummers to achieve a consistent tuning. Drummers can tune drums "by ear" or, in the 2010s, use a digital drum tuner, which "measures tympanic pressure" on the drumhead to provide accurate tuning.
There are many different types of keyboards available. On the lower end are keyboards that you’d find in a toy store, while music stores have keyboards that are more fully-featured and intended for serious musicians and producers. These types of keyboards are commonly loaded with different voices, tones, rhythms, and sound effects to give a player or producer a lot of control over their sound. Within this type of keyboard, you’ll find synthesizers and MIDI controllers. Another differentiator among keyboards is the number of keys. Some keyboards have fewer than the traditional 88 keys you’d find on a digital piano. This allows certain keyboards to be more compact and generally doesn’t impact the ability for the player to create music. While some keyboards have keys that are weighted, many do not. This means that keyboards do not move or react like piano keys.
As with any instrument, the perfect digital piano for you is going to be based on one part function and two parts preference. It doesn't matter if you're a beginner or a master pianist: the first step to your new digital piano is simply to decide which one suits you best. With that accomplished, you're well on your way to making the next step in your career with a brand new instrument you can truly call your own
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.
Chords are not used that often by electric bass players. However, in some styles, bassists may sound "double stops", such as octaves with open strings and powerchords. In Latin music, double stops with fifths are used. Robert Trujillo of Metallica is known for playing "massive chords"  and "chord-based harmonics"  on the bass. Lemmy of Motörhead often played power chords in his bass lines.
All of these are classified as non-pitched percussion, allowing for the music to be scored using percussion notation, for which a loose semi-standardized form exists for both the drum kit and electronic drums. The drum kit is usually played while seated on a stool known as a throne. While many instruments like the guitar or piano are capable of performing melodies and chords, most drum kits are unable to achieve this as they produce sounds of indeterminate pitch. The drum kit is a part of the standard rhythm section, used in many types of popular and traditional music styles, ranging from rock and pop to blues and jazz. Other standard instruments used in the rhythm section include the piano, electric guitar, electric bass, and keyboards.
An LCD readout and a few more buttons on the control panel would go a long way toward making the keyboard’s options easier to use. The metronome function especially could be more user friendly. It has 10 speed presets, labeled 0-9, with a + and – for adjustment. These are selectable with the Function button and a key press. While practicing and deciding on tempo, most students find it more beneficial to know the exact BPM (beats per minute), which is impossible here using the built-in metronome.
The smallest and largest drums without snares, octobans and gong drums respectively, are sometimes considered toms. The naming of common configurations (four-piece, five-piece, etc.) is largely a reflection of the number of toms, as only the drums are conventionally counted, and these configurations all contain one snare and one or more bass drums, (though not regularly any standardized use of 2 bass/kick drums) the balance usually being in toms.
Just like the acoustic instruments they're derived from, digital pianos come in different sizes. They also offer dozens of options for your perusal, so you can weigh all kinds of factors to find the right model for you. For instance, if you're looking to pack a lot of piano into as small a space as possible, consider instruments such as the Williams Allegro 88-Key Digital Piano or the Casio CDP-120. These are fairly compact pianos, but that doesn't limit the breadth of their samples and sound settings.
