What I find truly interesting is that the people who really have a strong sense of pitch don't need to advertise that fact. In general, every time you hear an audition from someone who lists "perfect pitch" as a skill on their resume, you can usually always bet on a flat or sharp performance. Oh, gosh. The most tone-deaf person I know claims to have perfect pitch. She says that she can 'pull any note right out of the air.' Eurgh.
Now, I know when my pitch is off, and sometimes it is, especially on breaks in my voice. Whenever I miss a note, I cringe, but I can't go back in time and fix it, so I guess I'm less harsh on singers who are flat, because I sympathize with them.
My sister and brother DO have perfect pitch, unlike me, and they go crazy whenever they hear anyone (including me or a famous singer) hit a bad note. Whenever I play a song with Terrence Mann singing, who I adore, my sister has to leave the room because she feels physically ill when he misses a note.
In my pants, she has burst like the music of angels, the light of the sun! --Marius Pantsmercy
