Alongside Recording Techniques, should there be something about singing technique in general, or would that be lumped in with recording technique? There are important things about singing that need to be considered when recording an UTAU, like keeping pitch consistent between samples(likewise, what note to sing on), breathy vs supported tone, other weird tone things like belting, screaming & falsetto, and enunciation/diction (especially with pronunciation guides!). Perhaps something about keeping your voice from getting tired or vocal warmups too.
