The theme of my work ‘Rejoice’ is the metaphorical representation of the transition to another reality, expressed through the juxtaposition of normal sound and harmonics. The possibility of producing different pitches at the same point on a string on a stringed instrument can be experienced in music as the transition to another level of reality. And such an experience is nothing other than joy. Flageolet tones have of course been used thousands of times and there is nothing extraordinary about this technique. Here, however, it is a matter of experiencing these tones not just as a timbre or a coloration, not as the clothing of a thing, but as its essence, the essence of its form as ‘transfiguration’. And only art can achieve this. (Sofia Gubaidulina)
