Satya IV is a clarinet solo written in 1981. It is a quieter, calmer work exploring particularly the low and middle registers of the clarinet. There are effective uses of harmonics in glissando in the cello and frequent drones, either above or below a moving melodic line, and splashes of pizzicato. The extensive solo cello sections are joined almost unintrusively by entrances of the piano with ensuing creation of tension and density. The piece is not a catalog of effects on the cello, but certainly they are all there, not to astound but to express Dinescu's unique sonar imagination.
Ostinato patterns are a bit rare, but they do occur, and are generally more tonal in nature.
The stellar performers are Wolfgang Boettcher and Ursula Trede-Boettcher. Lichtwellen is for clarinet solo, and dates from 1991. Aretusa is for violin solo, written in 1988, and performed by Dora Entcheva. Not having the score, I nevertheless assume that a great deal is left up to the performer in interpreting the music. This extended work is, in general, more tonal.
