Energy class based on an earthquake's seismic energy, although S. L. Solov'ev seems to have made major contributions. (In contrast to the "Richter" and other magnitude scales developed by Western seismologists, which estimate the magnitude from the amplitude of some portion of the seismic waves generated, an indirect measure of seismic energy.) However, proper estimation of E requires more sophisticated tools than were available at the time, and Bune's method was unworkable. A more practical revision was presented by T. G. Rautian in 1958 and 1960; by 1961 K-class was being used across the USSR. A key change was to estimate E
Recomposed by Max Richter: Vivaldi – The Four Seasons Recomposed by Max Richter: Vivaldi – The Four Seasons Recomposed by Max Richter: Vivaldi – The Four Seasons is the 2012 album by neo-classical composer Max Richter, released on August 31, 2012 on Universal Classics and Jazz (Germany), a division of Universal Music Group, and Deutsche Grammophon.

Although Richter said that he had discarded 75% of Vivaldi's original material, the parts he does use are phased and looped, emphasising his grounding in postmodern and minimalist music. The album was composed by Max Richter, played by the violinist
