This advertisement for Soundfly has casting directors and top Broadway talent saying the damn truth: If you want to be a successful musical theater performer, you've simply got to get comfortable reading music, knowing basic theory, and sight-singing.
Their program looks great, and there are lots of other resources online to study these topics. Some people prefer to do the work 1-on-1, and at All Voices + Musics, music reading, theory, and sight-singing are integrated into the work that we do in lessons and coachings. And it actually can be fun, believe it or not!
Everyone has an individual learning style, and taking a course like this one offered by Soundfly, learning from a book, using an app on your phone - alongside private lessons or coachings - is a brilliant way to elevate your performance -- and to empower the hell out of yourself as a musician!
"If you can learn to read music, you are on a whole different level than everybody else that's on Broadway." – James Monroe Iglehart (Tony Award Winner, Aladdin, Hamilton)
