it's very hard to adequately teach yourself piano, voice, any instrument, without getting into bad habits that you aren't aware of. why not try a vocal class at a community college. or, a chorale. in a chorale, you learn everything - to sightread, to blend in, you're not put on the spot (unless you are the only one - after a month- singing wrong notes), and it's fun. also, it helps you learn to sing at your loudest (which many beginning singers are too shy and sing very softly by themselves - thus, never really learning how to get the vocal chords going) many people sing from the throat. you can see it while they are singing. you're supposed to sing from the diaphram, but not everyone learns this at the beginning. it takes a lot of energy. you have to learn how to breath properly. warm ups with a choir help you to learn what to do at home. and, you can get tapes and sing along (or make your own). plus, you learn good repertoire and not the boring beginning songs over and over.
