Many students have a hard time choosing a song to work on during our time together. Because there are so many songs to choose from, here are my criteria for choosing a song that challenges you.
The song must have a variety in melody. It doesn't just stay in one comfortable place. It moves and challenges you to stretch higher or lower in your range.
The song has good technique. In other words, can you understand the singer, or are they so bogged down with vocal effects and ornaments that you can't figure out the melody or words?
By far the most important is that you have an emotional connection to the song. This will keep you enthused in the song, even when the going gets rough.
If you still can't think of anything, no worries. I created the Octave Higher Mix Tape just for you. The Octave Higher Mix Tape is a collection of songs with good vocal technique and ranges in difficulty from easy to hard. Now you can choose from more than 100 songs!
