I used to have a friend growing up that loved to sing. He just loved it – his whole family did! Unfortunately they were all completely tone deaf. They couldn’t hit a note if their lives depended on it.
Due to their exhuberance, I always felt uneasy about mentioning this to them, so I suffered through their performances.
Alas, that was some 30 years ago, and tests like these were not easily around. If they had been, then maybe I could have just sent them this link as a subtle hint to their aptitude.
There’s three tests: pitch, rhythm, and tone. My results? Rhythm 76%, Tone 83.3%, and Pitch…
Good luck!
