Instrumental Duet Harp,Instrumental Duet,Violin - Level 5 - Digital Download SKU: A0.875775 Composed by Maurice Ravel. Arranged by N. Szederkenyi. 20th Century. Score and parts. 34 pages. IStrings #3676277. Published by iStrings (A0.875775). This work is a transcription for violin and harp of Ravel’s amazing La Valse. This Viennese valse in Ravel’s unmistakeable language is a great challenge for both, violin and harp due to the fact that a huge modern orchestral score has been reduced to these two instruments. This is most likely at the high end of technical demands, especially for the harp.
