(a) Stimulus example of condition (1) regular vowel changes in musical notation. Quadruple measure groupings with a duration of 4 sec. (1 beat per sec.; 8 vowels alternately /a/i/) sung at a frequency of 220 Hz (A3), fMRI post-minus pretreatment results; (b) stimulus example of condition (2) regular vowel changes with rests in musical notation. Quadruple measure groupings with a duration of 4 sec. (1 beat per sec.; 8 vowels alternately /a/i/) sung at a frequency of 220 Hz (A3), fMRI results, upper row: pre-minus posttreatment and lower row: post-minus pretreatment; (c) stimulus example of condition (3) irregular vowel changes in musical notation. Quadruple measure groupings with a duration of 4 sec. (1 beat per sec.; 8 vowels alternately /a/i/) sung at a frequency of 220 Hz (A3) fMRI post-minus pretreatment results of Mr. U.
