If you are looking for unique 20th century melodic etudes which incorporate a variety of technical issues, the 24 advanced etudes by Louis Julien Vannetelbosch (1920-2000) may be just the right choice. Even a first glance at these etudes will reveal the creative and distinctive qualities of these pieces with their frequent tempo changes, multiple stylistic sections and other technical features such as: changing meters, asymmetrical meters (5/4, 7/4, 7/8), ornamentation (grace notes), wide interval slurring, flutter tonguing, complex rhythms such as 16th and 32nd note combinations, and mostly playable keys with a few etudes including up to 4 sharps/4 flats. Overall range is moderate, but there is a consistent exploration of the low register and occasional ascension to and above high C. Includes well-detailed dynamic, articulation and other musical notations to encourage expressive playing. 22 pages. -pc
