The number seven app on Apple’s all-time top 20 paid downloads list, which we’ve dropped to number 10 in terms of gross income due to its low price of 99 cents, is Shinya Kasatani’s PocketGuitar. PocketGuitar is Kasatani’s only app in the App Store, but it seems to have done quite well for both himself and Apple.
PocketGuitar turns your iPhone into a virtual guitar, complete with frets, six strings, and six instruments: acoustic-electric guitar, electric guitar, classical guitar, muted guitar, electric bass, and "ekulele." PocketGuitar also has effects including distortion, chorus, and delay. There’s even an option for setting a variety of alternative tunings.
PocketGuitar is just one of many music apps available in the iPhone App Store. Another music app, Ocarina, creates a virtual flute that you play by breathing into the microphone and tapping flute notes on the iPhone. Ocarina has also been a success for Apple and its developers and currently holds the 14th spot in Apple’s all-time top 20 paid downloads list. Other virtual musical instruments in the iPhone App Store include piano, organ, sitar, drums, trumpet, trombone, saxophone, flute, clarinet, violin, cello, other implementations of guitar and bass guitar, and even harp (perhaps we’ll take a closer look at virtual musical instruments in a future article).
