After your first singing lessons (and subsequent ones) what do you learn?
How do they teach you to warm up your voice and do exercises? Is there something I can do to go to a first lesson with some knowledge or preparation?
try and hold a long loud steady pitch that doesn’t hurt. Then shift an ‘interval’ to another note. use a piano to confirm you’re in tune. try making the transition from one note to the other as seamless as possible. etc.
