haha im a drummer-vocalist too but anyway. seriously, unless u really wanna go pop or sth. DONT take vocal lessons. waste of money la. i doubt u are tone-deaf, as long as ur not tone deaf, dont need trainer. and abt the voice changing thing. that's bs. wont happen. lol if it were true then i wld have been able to see the vast difference in my choir already. and yah, good to know tt u've improved. and dont worry abt ur voice losing its "lowness", all i have to say is practise regularly, keep in touch with tt side of ur voice. practise a wide variety of songs with different pitches and keys. this increases ur voice's flexibility and range. yup. and for those who really wanna have vocal lessons, go to jj's one. the ocean butterfly. heard they're quite a good company. they give dance classes and whatsoever too.
