Thank you for viewing. This is a score of Mozart's Clarinet Concerto by Boosey & Hawkes, with piano accompaniment. Mozart's Clarinet Concerto is originally performed on an A clarinet, but this score is written for a B♭ clarinet. Compared to the Bärenreiter edition, the piano accompaniment has more notes, and I personally felt it was closer to the orchestral sound, so I purchased this score at the time. I think this is a perfect score for those who do not have an A clarinet but want to play Mozart's Clarinet Concerto, or for those who are particular about the sound of the piano accompaniment. Although it is unused, it has been stored out of its packaging, so there are scratches and scuffs on the cover due to aging. Therefore, I have listed the product condition as "Like New". Thank you for your understanding.
