We are all here because we love music and bass obviously, but is there an instrument that just makes you cringe every time you hear one? I'm not talking about just having a disdain for an instrument because you couldn't play it well; I'm talking about fingers-on-the-chalkboard or break-your-finger-changing-the radio-station annoying. For me it is the recorder. There can't be a more annoying sound than a room full of recorders just piercing my eardrums with shards of painful squeals and high C's. What instrument when you hear it (if any), just rubs you the wrong way?
