The music produced on a violin has, for centuries, been expressed through classical composition and techniques.The long history of music since the violin was invented in the early 16th century in Italy reveals how a variety of musical interpretations have evolved on this instrument. It continues with modern compositions today.
Instruments of approximately 300 years of age, especially those made in Italy by Stradivari and Guarneri del Gesù, are the most sought after instruments (for both collectors and performers). The Ave Maria (Bach - Gounod) clip above is performed on the ex-Napoleon/Molitor Stradivari Violin.
There has been an effort, examined on this website from a French violin maker, to illustrate the charted climate variations during the last 600 years with a violin. The composition expresses the graphics of the rising global temperatures in an intuitive movement showing this progression using an electric violin. It's a direct evocation of the changes experienced on this planet through the sonic rendition of the historic temperature cycles.
The expression of harmonic scales and integral ratios of the octaves underlie a deeper understanding of the structure of music that explores the fundamental behavior of all other materials and living things and their relationship with the interconnecting energies of the physical world. It's the sonic mathematical equivalent of quantum physics and the geometry of shape, size, relative position of figures and the properties of space, just as colors are a song in light, seen across the spectrum as a rainbow.
It's all harmonics.
