Examples of complex gestures and decorrelation of parameters from the work "Quattro variazioni sul ritmo del vento" by Agostino Di Scipio for Amplified Paetzold Contrabass in F and Live Electronics.
These examples have a peculiar notation in which the upper 5-line staff indicates the key positions and action made by the hands and the second one-line staff indicates the actions to be made with the mouth (breathing, articulations, etc...) and the last 3 lines are employed as a notation for electronics.
This is very useful to describe some gestures which don't require a regular coordination between breathing, mouth articulation and movement of keys, as to produce strange and new sounds.
This is a clear example of decorrelation and an explanation of notation:
These requires the use of the mouthpiece only, detached from the instrument:
This employs the use of keys like a percussion:
These also require action on labium:
Singing in the instrument, voice and sound:
In this example from "Seascape" for amplified Paetzold Contrabass in F by Fausto Romitelli there is a conjoined virtuosity of both voice and instrumental part.
