Choir is a brilliant music making game in which you get to control an entire choir to create some beautiful melodies. You can play this game online and for free on Silvergames.com. Take control of this four part harmony choir and check out the different chords you can play to build fascinating sounds with. The different chords you can release were specifically selected for you to easily make great compositions.
Just grab the lower lip of the lead singer, who by the way sings in higher tones than the others, and keep sliding it down to trigger different notes. Of course, the other backing, lower voices will add their respective notes to it in order to create such amazing sounds. Try it out and create your own compositions. Have fun with Choir!
