Cadenza 1: Using the A string as a basis, and repeatedly striking it, play various double notes (sixths, fourths, thirds, seconds) increasing in speed and volume, up to very high pitches (about sixth octave). At the climax pass into unharmonious single-runs* (loud, brilliant, fast) and lead these organically down to the following target point:Cadenza 2:High and highest softly and tenderly (smoothy) whistling long harmonics (flageolets) ad libitum. (Also artificial harmonics, maybe even double notes) as long as the tension of the player and listener can be kept.*I don't really know what he means with single-runs
Anyone wondering, how you can play double stops (sixths, fourths, thirds, seconds) using the A string as a base...? On the Cello... ?
The A string is the highest string on the Cello, isn't it?
Anyone wondering how someone could not understand what the composer meant by "base"...? On a music forum...?
It is a lesson of one of the deadly sins in translation: "error of omission" - the word "leer" was omitted in the first attempt.
