Valse Sentimentale is in ternary form, in 3/4 time and romantic in nature The first section is a gentle waltz in Concert G minor minor and the second section by contrast is in E flat major and takes on a barcarolle like quality but remaining in 3/4 not the traditional 6/8. It returns to section one again and the coda brings back a short reminder of the barcarolle theme in G major to finish. The range of the clarinets are around two octaves with the top note- top E flat appearing once. Each part is equally divided to avoid the 1st clarinet and 2nd definition. I have set it to early intermediate level but the whole score is on the youtube link for you to assess. It would work well for a variety of occasions. It is around 5 mins 50 in length.
