Over a decade ago, he became interested in spectral composition and eventually began to study at Columbia with one of the founders of the compositional trend, Tristan Murail. Spectral concepts are based on modern mathematical and instrumental analyses of the sound spectrum, but the roots of the attitude towards music go way back into the twentieth century, to the work of composers such as Edgard Varese, or, more recently, Karlheinz Stockhausen, most notably his work Stimmung. The spectralists seek to analyze the components of each sound, which is made up of individual partials (periodic waves), and to utilize this knowledge in the creation of melody and harmony. As Lehman once explained it, "one could perhaps say that spectral music is largely concerned with the project of using timbre and the physical properties of acoustics as models for a variety of compositional technique."
In 2009 Lehman offered the fullest realization of his spectral work on the octet album Travail, Transformation, and Flow. Here his compositions use timbre, harmony, melody, and rhythm as equal elements, not as layers, and individual improvisation blends with the vibration of the ensemble. The harmonic rhythm is often derived from non-jazz sources, and it is rarely predictable, with repetition skipping into something else at every turn. Sound is as important as melody, with the overtones of instruments blending in unique ways.
The Steve Lehman Octet plays at the U-M's Lydia Mendelssohn Theatre on November 9.
