A movement in this musical form titled “Quaerendo (-5[1])invenietis” ("kway-REN-doh in-veh-nee-AY-tiss”) instructs a performer to turn their music upside down as if using a mirror. In a piece in this form, the violins play dux ("DOOKS”) and comes ("COH-mez”) parts over an ostinato beginning (read slowly) “D, down to A, up to B, down to F-sharp.” Every third movement except the last of J. S. Bach’s Goldberg Variations is in this form, whose “crab” type uses (-5[1])a retrograde voice. A gigue ("ZHEEG”) is paired with a piece in this form that features a bassline that is repeated 28 times. (10[1])A round is a type of this form in which the same melody (10[1])is sung at different times. (-5[1])For 10 points, (-5[1])name this musical form of a widely performed (10[1])Johannes (10[3])Pachelbel piece “in (10[3])D.” ■END■
