29.
A low-frequency sound or instrument which is used to enhance music or provide some sort of musical ground. Most modern music uses electronically-generated bass synths, while traditionally-created music uses low-frequency instruments for the bass.

Bass can also be referred to an audio setting that makes the low frequencies of a song more pronounced.
The bass was set so high the stereo speakers got fried when the next song began to play.

A misunderstood and underestimated instrument. Some retards with no musical sense think that a bass player is a lesser form than a guitar player but they don't realise that in many songs, a guitar would sound very shitty without the bass. Same goes for the guitar, a bass sounds... boring without a guitar. The two go hand in hand, whether added synthetically or actually played. I am a bassist and I have never layed hands on a guitar, they just don't interest me. So alot of bassists aren't failed guitarist. I chose to be a bassist because I love the sound and have an appreciation for its importance.
Flea! Whoo hoo!

God. God played bass. It's as simple as that.
God was the drummer for "Heaven", until their bassist, Lucifer, got fired. Then, God had to fill in for Lucifer on bass.

3: Any other instrument or item that emits low-pitched, rumbling sounds. Ex.: A bass trombone, bass-boost speaker system, and so on.

an instrument shaped, held, and fingered much like a guitar, only cooler. bass players happen to be much much sexier than guitar players, despite popular belief. i would bang any bass player in a second, provided he was any good. double points if he's british..
Lisa: that guitarist is a glory hog, but the bass player is talented
Me: and damn sexy.
Lisa: agreed.

1. Instrument designed as a modern replacement for the Double Bass (or Contrabass or Upright Bass or String Bass or whatever you wanna call it). It is tuned the same as the Upright Bass (or Contrabass or Double Bass or String Bass) or an octave lower than the bottom four strings of a guitar (both mean the same thing, so it's not that big of a deal what you say).
2. A fish.
1. Anyone who thinks bassists are failed guitarists should probably be shot.
