TonesÓ - a laboratory for the harp (2011)
http://en.wikipedia.org/wiki/Laboratory
A laboratory (pronounced /ləˈbɒrətəri,
ˈl¾bərətri/; informally, lab) is a facility that provides controlled conditions in which scientific research, experiments, and measurement may be performed. The title of laboratory is also used for certain other facilities
where the processes or equipment used are similar to those in scientific
laboratories.
http://en.wikipedia.org/wiki/Shepard_tone
A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine
waves separated by octaves. When played with the base pitch of the tone moving upwards or downwards, it is referred to as the Shepard scale. This creates the auditory
illusion of a tone
that continually ascends or descends in pitch, yet which ultimately seems to
get no higher or lower.[1] It has been described as a "sonic barber's pole"
http://en.wikipedia.org/wiki/Acronym_and_initialism
Acronyms and initialisms are abbreviations formed from the initial components in a
phrase or name. These components may be individual letters (as in CEO) or parts of words (as in Benelux and Ameslan). There is no universal agreement on the
precise definition of the various terms (see nomenclature), nor on written usage (see orthographic styling). While popular in recent English, such
abbreviations have historical use in English as well as other languages. As a type of word
formation process,
acronyms and initialisms are viewed as a subtype of blending.
