The Four Orchestral Pieces (1912), which Boulez is credited with rescuing from obscurity in the Seventies, amount to a dazzling showcase of Bartók's influences and their reinvention: harmonic echoes of Debussy and Mahler, Stravinsky and Schoenberg underpin his reworking of Hungarian folk themes as his own distinctive brand of modernism.
When Designblok attendees crossed the beams with their hands and bodies, they triggered melodic loops of rhythmic patterns, harmonic echos, and street sounds.
Some only a couple of bars long, these pieces have the aphoristic playfulness of Kurtag's piano miniatures, and through harmonics, echo effects, and double-stopping they conjure up vast spaces through which the drama – and this really is a drama – moves.
Mr. King writes of harmonics, echoes and "the butterfly effect," two ways of saying that tampering with the past is a dangerous business.
During the chorus, the Edge's backing vocals further develop this tread, using a harmonic imitative echo.
We removed harmonics and echoes with the callViewer signal to noise ratio filter.
In his richly chromatic, acutely rendered harmonic vocabulary, you hear echoes of Mahler, Strauss, the Debussy of "Pelléas et Mélisande," the Berg of "Wozzeck," the neo-Classical Hindemith.
The study is the culmination of the six-year program "Accelerator R&D for a Soft X-ray Free-Electron Laser: Echo-Enabled Harmonic Generation," which was funded by the DOE Office of Science, Basic Energy Sciences.
The drive laser system used for photocathode gun research at ASTA will also be used in a separate effort to develop laser techniques for echo-enabled harmonic generation, which can produce highly tunable X-ray laser pulses.
When a US wave reaches the agent, they show asymmetric oscillation, producing echoes containing harmonic frequencies [4], which are signals with frequency peaks at multiples of the transmitted frequency.
