Musical Theatre: Singing Techniques


Learn techniques for eliciting the best vocal performance of a song from acclaimed Broadway actor, singer, and performer Sydney James Harcourt (Hamilton, Lion King, American Idiot, Girl from the North Country).

You'll learn practical and effective ways to prepare for a performance, including vocal warm-up exercises and strategies for managing your breath, mapping who you are to the meaning of a song, and crafting the emotional arc of the song. 

All throughout the course, you will receive personal feedback from your instructor, and also gain self-awareness to help in evaluating your own performances and making adjustments to improve them. You'll also gain insights of what is expected at professional auditions and tips to stand out.

The goal of the course is to prepare you for your next performance, whether it is an audition or a production you are already cast in, so that you triumph.

What you will learn:

✔ Develop a routine that includes practical and effective vocal warm-up exercises   
✔ Improve your performance of a song by identifying vocal transitions, preventing consonants from impeding your vocal production, and developing ease with phrasing   
✔ Make effective use of dynamics to heighten the emotional impact of the vocal performance   
✔ Develop strategies for understanding the meaning of a song, memorizing it, and delivering it authentically   
✔ Evaluate your own performance and make adjustments based on feedback from others   
✔ Gain strategies to ensure you are prepared for professional auditions
