Teppo Hauta-aho . Written to celebrate the 80th birthday of the American bassist and teaching, David Walter, this offers many challenges for the adventurous bassist. It uses much of the range of the solo double bass, including harmonics, double stops and optional improvisation, with much to explore both musically and technically. Lyrical and dramatic by turns, this is colourful and atmospheric writing, full of rhythmic invention and momentum. Many opportunities to demonstrate more than simply technique and an excellent example of the work of this leading Finnish bassist-composer.. Performance Level: Advanced.. Grade: Advanced
