Here are some YouTube playlists that I update every so often with ideas for Songs/Audition Materials from Musical Theatre. These areas are simply the most "in-demand" - mid range Soprano (intended for younger singers that may not be confident in their higher range, yet, but don't have super low notes, either). Eventually, I hope to post a selection for a wider variety of voice types/needs.
Special thanks goes to my talented students who have brought current hit and cult shows to my attention in recent years! If there is something particularly "audition" or "concert" worthy that is not on these lists (especially for mid-range soprano students), please let me know and I'll add it to a playlist!
