And now, a couple recent items — both related, in a way, to dramatic changes in pitch — for those brave souls willing to follow me out to my geekiest musical fringes.

From the audio engineer: at Tape Op, “In defense, unsuccessfully, of Autotune,” wherein I ultimately give up and instead go on a Google expedition to find the haunting voice from the competing software‘s demo video.

From the academic: at Indaba, a comparison of approaches in pop and jazz for analyzing key changes.
