Six Week Mentor-Guided Course

Money‑Back Guarantee

What do you do in an audition if the casting director asks you to read a piece of music you've never seen before? Too many actors are totally unprepared for this and related situations. Knowing how to read music can give you a critical step up above the competition in your auditions.

Using examples from pieces you might already know and love, this six-week course will teach you the TheoryWorks six step process to approach any new piece of music from scratch and make it your own. In the process you'll learn about pitches, note values, time signatures, and much much more — getting weekly personalized feedback from an expert Soundfly Mentor along the way. By the end of this course, you should be ready for any sheet music obstacle your next audition throws your way.

Who is this course for?

This course is specifically targeted at actors and singers who don't feel comfortable with music theory or reading music. And yes, we know there are a lot of you out there. In the course you'll learn about how to read pitches on a staff, how to learn rhythms via notation, and even how to plunk out parts on the piano to support yourself as you practice. For those aspiring to Broadway, this is your chance to fill in the gaps and make yourself even more prepared. 

Is there a money-back guarantee? 

YES. If you sign up and the course isn't what you expected, we will give you a full refund as long as you tell us before the start of the second week. The reason that the second week of the course is a cut-off for our guarantee is simply because if we go past that deadline, our mentors will have likely put in a lot of time, energy, and effort already. 

We're also happy to move you to a subsequent session, if you end up not having as much time as you expected. Once again, let us know as soon as possible! 

What will I learn?

So much! This course is packed with content — maybe even too much! (But it's OK because you can go at your own pace). You will learn how to read and understand a score, how to read rhythms from notation, how to self-conduct, how to plunk out easy melodies on the piano, and how to put it all together into a coherent performance. 

Are there any pre-reqs? 

Nope! Anyone is welcome, and no prior knowledge of sheet music is assumed. If you feel like you do already know some things but just need to stand on firmer ground, that's fine too. You're welcome to skip through the stuff you know, and focus on the stuff you need more work on. 

What do I get as a Mainstage student? 

The Mainstage experience is built on our science-backed active learning model, which helps you learn more efficiently and effectively than typical online courses. The key difference is our mentorship approach — one-on-one coaching with a trained Soundfly Mentor who has extensive experience in the subject. When you sign up, we'll pair you with an expert who will tailor the course to your experience level, offer detailed weekly feedback on your work, answer any questions you have, help you blow past obstacles, and keep you on track to accomplish your musical goals.

You'll also get unlimited, lifetime access to all the course content — including in-depth lessons, activities with answer keys, quizzes, video tutorials, and downloadable resources — so you can review anytime and keep your skills sharp.

As an extra perk, you’ll get lifetime access to our tight-knit musician community group on Slack, where you’ll find peer-to-peer feedback and support, lots of inspiration, and fun, musical conversations with fellow Soundfly students, mentors, and staff.

What does it mean that the course starts on a specific date?

As soon as you purchase a course, you can begin exploring the course material immediately. On the start date, the session begins, which means you'll begin a guided experience that includes weekly activities, feedback from a Soundfly Mentor, and much more. This is intended to help you stay accountable and get the feedback you need to succeed. 

Will there be future sessions of the course?

Yes! Check back shortly for firm dates, or sign up for a Soundfly account to receive email updates about course dates and new course launches.
