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, (10[1])the violins play dux (10[1])("DOOKS”) and comes (-5[1])("COH-mez”) parts over an ostinato beginning (-5[1])(read slowly) “D, down to A, up to B, down (10[1])to F-sharp.” Every (10[1])third movement except the last of J. S. (10[1]-5[2])Bach’s (10[2])Goldberg Variations is in (10[1])this form, (-5[1])whose “crab” type uses (10[1]-5[1])a (10[3]-5[1])retrograde voice. (10[1])A (10[1])gigue (10[1]-5[1])("ZHEEG”) is paired with (10[1])a piece in this (-5[1])form that features a bassline that is repeated (10[2]-5[1])28 (10[1])times. (10[1])A round is (10[1]-5[1])a type (10[1])of (-5[2])this form in which the same melody (10[1])is sung at (10[1])different (10[1])times. (-5[1])For 10 points, (-5[1])name (10[1])this (10[1])musical form of a widely performed (10[4])Johannes (10[3])Pachelbel piece (10[2])“in (10[15])D.” ■END■
