Just ideas, some maybe silly, since I am not at all in depth of singing (I like your blog; read most of it last night!)
•Differences in methods/techniques in musical genres
•Reading music
•Voice and aging (Madonna’s voice sounds much more deeper/mature within the past ten years while other aging singers sound the same)
•Mixing genres (Shania Twain country/pop)
•Learning to sing with a learned accent
•Seeking a mid nasal voice (maybe Raspy voice)
•Lyrics: creating, using, changing, making them your own
•Don’ts about singing
•When to know you’re on the right track (progressing) rather than standstill
•Imagery
•Best of… (books, movies, anything that will help a singer in training)
•Control over performing (dancing, moving) and voice at the same time
•How the physical body affects voice (weight, fitness, overall health); not sure about this one.
•Mentality, psychology, for optimal development
•Trying to reach a certain style/ ambiance
•Captivating the audience without making them feel sorry for you, bored, irritated, other negative emotions
•Most common problems
