The hi-hat cymbals (nicknamed "hats") consist of two cymbals mounted facing each other on a metal pole with folding support legs that keep a hollow support cylinder standing up. Like the bass drum, the hi-hat has a foot pedal. The bottom cymbal is fixed in place. The top cymbal is mounted on a thin pole which is inserted into the hollow cymbal stand cylinder. The thin pole is connected to a foot pedal. When the foot pedal is pressed down, a mechanism causes the thin pole to move down, causing the cymbals to move together. When the foot is lifted off the pedal, the cymbals move apart, due to the pedal's spring-loaded mechanism. The hi-hats can be sounded by striking the cymbals with one or two sticks or just by opening and closing the cymbals with the footpedal, without striking the cymbals. The ability to create rhythms on the hi-hats with the foot alone enables drummers to use both sticks on other drums or cymbals. Different sounds can be created by striking "open hi-hats" (without the pedal depressed, which creates a noisy sound nicknamed "sloppy hats") or a crisp "closed hi-hats" sound (with the pedal pressed down). As well, the high hats can be played with a partially depressed pedal.
Bass solos are performed using a range of different techniques, such as plucking or fingerpicking. In the 1960s, The Who's bassist, John Entwistle, performed a bass break on the song "My Generation" using a plectrum. He originally intended to use his fingers, but could not put his plectrum down quickly enough. This is considered as one of the first bass solos in rock music, and also one of the most recognizable. Led Zeppelin's "Good Times Bad Times", the first song on their first album, contains two brief bass solos, occurring after the song's first and third choruses. Queen's bassist, John Deacon, occasionally played bass solos, such as on the song "Liar". Metallica's 1983 debut Kill Em All includes the song "(Anesthesia) Pulling Teeth," consisting entirely of a bass solo played by Cliff Burton.
Among digital pianos, there are several differences. The three main types of digital pianos are standard digital pianos, upright digital pianos, and stage pianos. Upright vertical pianos are built with a large cabinet, not unlike a real upright piano. They are often fitted with the best hammer action key systems and tone generation engines so that they are comparable to real upright pianos. Obviously, they still take up as much space as a real one, but there is less maintenance required. Stage pianos are digital pianos designed to be used in live performances, or on stage. They are much more portable than traditional pianos, and much sturdier than standard digital pianos. Standard digital pianos are intended more for practice and play at home. They are not as large or fully featured but offer an excellent balance of sound and portability.
The standard design for the electric bass guitar has four strings, tuned E, A, D and G, in fourths such that the open highest string, G, is an eleventh (an octave and a fourth) below middle C, making the tuning of all four strings the same as that of the double bass (E1–A1–D2–G2). This tuning is also the same as the standard tuning on the lower-pitched four strings on a six-string guitar, only an octave lower.
Strumming, usually with finger nails, is a common technique on acoustic guitar, but it is not a commonly used technique for bass. However, notable examples are Stanley Clarke's bass playing on the introduction to "School Days", on the album of the same name, and Lemmy who was noted for his use of chords, often playing the bass like a rhythm guitar.
Regardless of the model or series, a bass typically has four strings. They are tuned the same way as the first four strings on a regular guitar: E, A, D, and G. Some musical genres have alternative tunings, though. For example, metal often uses "drop D" tuning, where the E on the lowest string is tuned down a step to D. Most alternative tunings involve tuning down. Some basses have a fifth string. Usually this is added to the low end, where it becomes a B in standard tuning. In rare cases. it will be added to the high end, where it is known as a tenor fifth string and becomes a C. In even rarer cases, a bass can have six strings, using both the low B and the high C. The neck of the bass can be comprised of woods that range from maple to rosewood.
The second biggest factor that affects drum sound is head tension against the shell. When the hoop is placed around the drum head and shell and tightened down with tension rods, the tension of the head can be adjusted. When the tension is increased, the amplitude of the sound is reduced and the frequency is increased, making the pitch higher and the volume lower.
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.
