Open to all young oboists up to 20 years old.

Mozart Concerto, K. 314, 2nd and 3rd movements only, any edition accepted.
We recommend any one of several:   Henle, as close to urtex as we have with excellent preface notes,  Barrenreiter  which also calls itself Urtex, and which includes comparisons with the flute edition transcribed by       Mozart himself in D Major for Frederick the Great.  The Peters Edition includes all orchestral cues and is available with a ‘CD Partner’ of the Orchesral accompaniment. The Wye edition has good notes on articulation and embellishment. Boosey has been fine for many of us for   many years, and is still just fine.

We also have cadenzas by John Mack, John Corina, Wuorinen.
Or write your own with the help of a book on writing cadenzas by Mather.

Do you get the message here?  We’ve all played this piece many times. Like all Mozart it is too hard for the pros and too easy for the students. Give this a lot of thought!  Someday I may share my very poignant lesson with Mr. Mack on the Mozart Concerto – without playing a note!

And there are three more pieces to your required list:

Paladihle – there is only one piece by Paladilhe and it goes by several titles: Concertante or Solo pour Hautbois most commonly.

A just published wonderful new Edition by Jeanne gives you copious notes on interpretation. Also aditions by Rubank, Masters, and Southern Music (in the Andraud collection). 
Any edition is acceptable.

Telemann – Sonata in Bb Major or ‘Sonate in B-Dur’ published by Schott.
I do not think there is any other edition of this particular Sonate except Schott.  Inside the front cover it says ‘from aus Essercizii Musici’.  It is not likely to be on your shelf.  (Not part of the Methodical Sonatas)

Andriessen – Ballade – published by Donemus, no other edition available.
Again you are not likely to have this on your shelf already. I think you will find it a stunning piece with the piano, and a different kind of difficulty from any of the above, a mature piece!
