Can you teach yourself to sing?
In the same way as any other artistic domain, singing lends itself perfectly to self-teaching. You can learn to listen to your own voice and correct the notes that are out of key, adjust your vocal cords and your vocal timbre, master breathing, then, bit by bit, you can start calling yourself a singer.
During singing, however, we need to inhale quickly and deeply, then exhale slowly and steadily, in a long breath, as we sing our phrases or notes. Singing requires a higher rate of breath energy than speaking does, as well as the elongation of the breath cycle.
