Portable electronic communication device. These have become robust platforms for digital audio production, composition, and music performance since the beginning of the 21st century. Recent compositions for mobile-phone ringtones might represent an emerging music genre. Since 2008, many commercial apps have transformed mobile devices into miniature synthesizers. Popular virtual-instrument programs such as Ocarina (2008) by the Smule Corporation and Band (2008) by MooCowMusic harness the phone’s numerous interfaces in various ways. Multi-point touch screens offer players the ability to manipulate graphical fingerholes, fretboards, drum pads, and keyboards, thus approximating the playing experience of acoustic wind, string, percussion, and keyboard instruments. Beyond its use in voice recording and transmission, a device’s microphone can register breath intensity, enabling users to initiate tones and alter dynamics as though playing a wind instrument.

Some mobile sound-production programs feature real-time voice manipulation, including auto-tune or pitch correction. Additional levels of musical functionality can be mapped to a phone’s accelerometer (an internal speed and direction detector). When the device is swung, shaken, or tilted, the accelerometer can trigger alterations in timbre, vibrato, pitch, and other variables. More advanced uses have been proposed. For example, a phone’s camera, acting as a real-time motion sensor, could affect many aspects of sound synthesis and sequencing; and the GPS (global positioning system) indicator has the potential to take location markers from other phones across the planet and turn those data into sonic information....
