The file "Musical examples" shows passages realised both with the tempered system and with the microtonal system. Clicking on "Listen the MP3" is possible to listen the musical passages, clicking on "Read the score" it is possible to observe various combinations of "drawing" of the sonorous lines on the monitor.

With PYMMusic they are not used pentagrams, clef, figures of value and relative pauses, divisions of the passage in bars... They draw lines on the monitor on which they are present 7 octaves (as in the piano, the central C is on the third octave). The monitor is horizontally crossed by lines corresponding to the frequencies of the selected sounds. The sound is produced when the cursor of the mouse is placed on the little square of the horizontal lines. It seems complicated, btu everything is semplified when it is thought that in order to write music with PYMMusic it is enough to draw lines (up and down on the monitor by hand free, with straight lines or with oblique lines in ascending or descending direction). The procedure is described by the user's guide of PYMMusic.

With reference to the microtonal sounds it is useful a premise. In the Dictionary of Music and Musicians by UTET (third volume, pages 133/134) it is dealt with the Microtone subject. It describes the attempts done in every time by researchers in every part of the world to be able to use the harmonies resulting by a further subdivisions of the tone. The subject ends with the verification that great musicians as Penderecki, Boulez, Stockhausen and Nono have been very interested in microtonal compositions.

From June 1st, 2005 PYMMusic has solved the problem in the realization of continuous and precise production of microtones, offering not only to musicians and researchers, but also to children (at least from the nursery school), disabled person, whoever ha s desire and interest of it the possibility to use third, fourth, sixth, eight and sixteenth of tone. Drawing on the monitor sonorous lines (up to sixteen, each one with a defferent colour) and submitting to as many preferred tools the preforming of themselves they are realised also complex scores audible in immediate and precise way. It is as if 16 instumentalist are available in each moment wothout problem of remuneration.

PYMMusic has opened boundless horizons in the world of the sounds.
