The Nintendo Entertainment System's audio processing unit (the Ricoh 2A03 chip) includes a Delta Modulation Channel (DMC) to demodulate percussion and sound effects. The DMC reads delta-encoded audio data via direct memory access into a shift register , which gets shifted out serially into an up/down counter acting as the demodulator's integrator.
The standard cümbüş is fretless, but guitar, mandolin and ukulele versions have fretboards. The neck is adjustable, allowing the musician to change the angle of the neck to its strings by turning a screw. [3] One model is made with a wooden resonator bowl, with the effect of a less tinny, softer sound. [4]
The effect can make these acoustic instruments sound fuller and louder than by using a single tone generator (b.e.: a single vibrating string or a reed). Some examples: Piano – Each of the hammers strikes a course of multiple strings tuned to nearly the same pitch (for all notes except the bass notes).
A resonator ukulele or "resophonic ukulele" is a ukulele whose sound is produced by one or more spun aluminum cones instead of the wooden soundboard (ukulele top/face). These instruments are sometimes referred to as " Dobro ukuleles," however the term "Dobro" is currently trademarked by the Gibson Guitar Corporation.
Guitar feedback effects can be difficult to perform, because it is difficult to determine the sound volume and guitar position relative to a guitar amp's loudspeaker necessary for achieving the desired feedback sound. [112] [113] Guitar feedback effects are used in a number of rock genres, including psychedelic rock, heavy metal music and punk ...
A slicer is an effects unit which is similar to a tremolo, vibrato, phaser, or autopan. It combines a modulation sequence with a noise gate or envelope filter to create a percussive and rhythmic effect like a helicopter, with rapid cutting out and coming in—on and off. [1] Most have variable speeds and depths, creating different sounds.
For example, a ii–V–I in C minor could be played as: Dm 7 ♭ 5 – G 7 ♯ 9 – Cm 7. The 7 ♯ 9 represents a major divergence from the world of tertian chord theory, where chords are stacks of major and minor thirds. The 7 ♯ 9 does not satisfy that definition, as the interval between the minor seventh and augmented ninth is an ...
The guitalele is variously marketed (and used) as a travel guitar or children's guitar. It is essentially a modern iteration of the Quint guitar. [5] A guitalele or guitarlele. A guitalele is the size of a ukulele, and is commonly played like a guitar transposed up to “A” (that is, up a 4th, or like a guitar with a capo on the fifth fret).
