i've been thinking about which instrument is the most powerful & effective and i've narrowed it down to 2, piano and voice. on piano you can play more than one note at once, you can be a one man band, you can't do that while singing but you can say words. you can combine language and music together. what's your opinion on this
that's pretty good, a lot of people do a very similar thing with an acoustic guitar+voice, instead of a piano. and that works very well too. some interesting advantages/disadvantages to each
