Multi-scale fingerboard is an alternative design for guitars and bass guitars in which the lower-pitched strings gain more length and the higher-pitched strings get shorter, similar to the string lengths on a grand piano. The reason for the uneven scale length across strings is that it evens out the tension across all of the strings, it evens the timbre across the strings, and extending the lower string scales allows the string to produce harmonics that are more in tune with the fundamental.
Snare drum and tom-tom Typical ways to muffle a snare or tom include placing an object on the outer edge of the drumhead. A piece of cloth, a wallet, gel, or fitted rings made of mylar are common objects. Also used are external clip-on muffles that work using the same principle. Internal mufflers that lie on the inside of the drumhead are often built into a drum, but are generally considered less effective than external muffles, as they stifle the initial tone, rather than simply reducing the sustain of it.
In 1971, Alembic established the template for what became known as "boutique" or "high-end" electric bass guitars. These expensive, custom-tailored instruments, as used by Phil Lesh, Jack Casady, and Stanley Clarke, featured unique designs, premium hand-finished wood bodies, and innovative construction techniques such as multi-laminate neck-through-body construction and graphite necks. Alembic also pioneered the use of onboard electronics for pre-amplification and equalization. Active electronics increase the output of the instrument, and allow more options for controlling tonal flexibility, giving the player the ability to amplify as well as to attenuate certain frequency ranges while improving the overall frequency response (including more low-register and high-register sounds). 1973 saw the UK company Wal begin production of a their own range of active basses, and In 1974 Music Man Instruments, founded by Tom Walker, Forrest White and Leo Fender, introduced the StingRay, the first widely produced bass with active (powered) electronics built into the instrument. Basses with active electronics can include a preamplifier and knobs for boosting and cutting the low and high frequencies.
The long scale necks on Leo Fender's basses—with a scale length (distance between nut and bridge) of 34 inches (864 mm) — set the standard for electric basses, although 30-inch (762 mm) "short scale" instruments, such as the Höfner 500/1 "violin bass" played by Paul McCartney, and the Fender Mustang Bass are also common. Short scale instruments use the same E-A-D-G tuning as a regular long scale instrument. Short scale instruments are good choices for bassists with smaller hands, such as children or young teens who are just starting the instrument. While 35-inch (889 mm), 35 1⁄2-inch (902 mm), and 36-inch (914 mm) scale lengths were once only available in "boutique" instruments, in the 2000s (decade), many manufacturers began offering these "extra long" scale lengths. This extra long scale provides a higher string tension, which may yield a more defined, deep tone on the low "B" string of five- and six-stringed instruments (or detuned four-string basses).
In most implementations, a digital piano produces a variety of piano timbres and usually other sounds as well. For example, a digital piano may have settings for a concert grand piano, an upright piano, a tack piano, and various electric pianos such as the Fender Rhodes, the Wurlitzer, and the DX electric piano. Some digital pianos incorporate other basic "synthesizer" sounds such as string ensemble, for example, and offer settings to combine them with piano.
1956 saw the appearance at the German trade fair "Musikmesse Frankfurt" of the distinctive Höfner 500/1 violin bass made using violin construction techniques by Walter Höfner, a second generation violin luthier. The instrument is often known as the "Beatle Bass", due to its endorsement and use by Beatles bassist Paul McCartney. In 1957 Rickenbacker introduced the model 4000 bass, the first bass to feature a neck-through-body design in which the neck is part of the body wood. The Fender and Gibson versions used bolt-on and glued-on necks.
Torzal Natural Twist is a bass guitar body and neck style invented by luthier Jerome Little from Amherst, Massachusetts. It consists of a neck rotated by a total of 35 degrees, with (+)15 degrees at the bridge and (-)20 at the nut. The designer claims that the ergonomic design increases efficiency of the hands, wrists and arms, which reduces the risk of developing repetitive strain injuries like carpal tunnel syndrome or tendonitis. This design is also beneficial to players who have already suffered from such injuries. This patented design differs from traditional bass guitar design by twisting the neck, and bringing the strings toward a more natural hand position at either end of the instrument. The rotation at either side of the instrument in the direction of the hand creates a neck plane that models the natural motion of the hand as it reaches outward. The fretboard also forms a straight line at the location of each string, which should improve the ease of performance.
Drums are used not only for their musical qualities, but also as a means of communication over great distances. The talking drums of Africa are used to imitate the tone patterns of spoken language. Throughout Sri Lankan history drums have been used for communication between the state and the community, and Sri Lankan drums have a history stretching back over 2500 years.
