In case you’re new here, we want to let you know that singing straight through a song is not practicing! Instead, we recommend you select a specific section of a piece to work over multiple times, starting, stopping, and rewinding while you practice a particular concept into in your voice, then log your practice time to keep track of what and how you’ve been practicing.
To facilitate this, write the timing of the practice track of different sections of the music in your score. Luckily, Nicholas Likos of Cy Fair High School has made an epic chart of all the time markers for this year’s music! Use this chart to write the timings in your score.
