I've been using these practice track videos with my middle school choir students as they prepare for the Wisconsin Solo & Ensemble Festival.
This is a zip file of two .mp4 videos of "A Legend" by Tchaikovsky, WI Solo & Ensemble Event 1121C3. One video is the melody played with quiet piano accompaniment, and the other is of the melody played with louder piano accompaniment.
I have received permission to sell these from Teachers Pay Teachers. They are for student rehearsal use only, and are NOT able to be used at Solo & Ensemble Festival as they are videos rather than sound files and because the melody is played along with the piano accompaniment.
To share these videos with your students, please upload them to a class website like Google Classroom, not to a service like YouTube.
