    Below data is based on following article, especially regarding the
    sounds of lowest C (C1) and the G1-4 keys:

    E. D. Blackham: "Klaviere", in: Die Physik der Musikinstrumente,
    Verständliche Forschung. 2. Aufl. Heidelberg; Berlin : Spektrum
    Akad. Verl., 1998
    — ISBN 3-8274-0291-3

    The data of the Railsback curve (octave stretch) has been taken from:
    Giordano, N. J.: Physics of the Piano, Oxford Univ. Press 2010, p. 61
    – ISBN: 987-0-19-954602-2

    Gradual mix-ins of "bumpslope", "smoothslope" and "fhdown" sustain phases
    are applied in order to make the sound more and more percussive and to
    serve the fundamental tone increasing dominance in the long run.
