The basic sound of my instrument, my voice, was that of a gentle oboe. it
had to be gradually amplified. I had to find more resonance to make it broader.
And this can of course, only be the result of long, painstaking work because
the instrument of the voice is invisible. One has to discover the correct
feelings to solve the technical problems and assimilate the process.
