That depends on the type of instrument you are talking about. An electric ukulele used pickups and no sound hole is required. However, an acoustic ukulele is going to need to have holes to provide volume by allowing the sound to project out of the instrument.
The tulali is a Filipino musical instrument that is a type of reed Flute. It has a single aperture, or hole, to place the mouth on and six others to place the fingers on.
A cajone is a drum-instrument consisting of a box with a hole in one of the sides, and guitar-strings inside.
There is no such thing as a reed flute; flutes have an embouchure hole that you blow across, down, into the hole, above the hole or straight on the hole. If a flute were to have a reed it would be held down, like the oboe or clarinet. There are, however, wooden flutes. If you are good at fingering on the flute but blowing on the reed, I suggest an oboe, as they are a reed instrument and have a similar fingering. The oboe is a very unique instrument. There are usually about 3 in a college band. Source(s): Band Geek :)
