The short choral singing exercise with harmony parts above is from the post 10 Elements that Impact Singing in Tune. Each sound track below acts as a harmonic sound model.
Specifically, singing along with the specially tuned sound tracks trains the ear to hear how well tuned chords should sound. I say the ear, but really it establishes the brain’s mental pitch template as you listen.
Let’s look at each part from the above score one by one. Even thought there is no break in the synth-vocal parts, take a breath before each note. If you run out of breath, your pitch can sink, making you go out of tune.
Start by singing the vowel oh, which blends well with the synth-vocal sound. When working on harmonic tuning, listen to the tone of the voice part.
Especially, listen for the amount of buzz between notes and any beating (the wah-wah-wah sound). If you hear beating, adjust your pitch until the beating fades away.
Here are the parts:
