I play to instruments:
The classic guitar
The air guitar (that's right, it is an instrument)
First, the number "2" is spelled T-W-O.
Second; only to the very pompous, ignorant, and self deluded can the "air guitar", be classified a, "musical instrument. Music, at its most basic, involves sound production. Air guitar produces no tonal information, either consonant or dissonant, therefore it can't be a "musical instrument".
You'd have better luck floating that BS fantasy past a group of arch nerds at a Star Trek Convention, as opposed to here, where you don't even get ignition, much less liftoff with that drivel.
And don't get me started about "Rock Band". That nonsense seems to be the same player-missile graphics as, "Whack a Mole"!
I would love to play an instrument but I haven't any talent or ability in me whatsoever to play anything that requires reading music.
Actually, "reading music" can be faked to one degree or another.
A minimal approach is to learn the notes on the "G" Clef, (treble cleff), and chord formations on the guitar or piano. Most sheet music is notated with the prevailing chord written above the staff. (At the point where the chord would change).
Then, working with material you're familiar with, you would read the top line of notes, (the melody), play it with your right hand, and finger the chords with your left hand!. (This is with piano, obviously). With familiar songs, the intricacies of note time value don't really affect the performance. That part is supplied from memory. With the guitar, it's a bit more difficult. In one scenario, you play the chords and sing the melody. The second is a bit more intensive, and involves a whole lot of practice, mostly finger picking and chord inversions.
But yes, playing the piano while sight reading two different cleffs and note timing with unfamiliar material is indeed an onerous chore. It requires years and years of practice. (Oh, and they expect to use your feet now and again, while you're doing all that too).
PS: I would have voted, but I don't know if they've figured out whether the piano is a string or percussion instrument. Meh, who cares? I can only play dribs and drabs on it anyway.
