HELLO I know the concerto in E major is played in D major for auditions.Which edition has the music read in D major,and also where to find the Gruber cadenzas for this concerto. Also, which edition has the piano part(transpose to D-orcheatra tuning). I heard Gruber cadenza 1st time on a old Streicher recording and boy,does it rock;it makes the "standard" cadenza sound very "junior-high". This dittersdorf concerto is asked quiet often in Europa and here in the states the NY phil.In both cases,the gruber cadenza is REQUIRED. Please help!!
