Musical notation

The most common graphic displays of interval and ratio information are X-Y plots, where distance in the display corresponds to distance on the relevant property or properties. Musical notation is a specialized interval scale that makes use of a limited visual alphabet corresponding to modes of execution of notes as well as a spatial scale corresponding to pitch. Finally, for displaying ratio information, pie charts can be useful,... 

At the base of any industry is the need to store information. Written languages, ideographic art, and even musical notation were developed for the purpose of passing knowledge on to others. At the most basic, any individual, company, or government division that uses a computer system relies on some form of magnetic storage to encode and store data. 

Composition. Aesthetic music compositions are typically layers of patterns that can be translated into mathematical expressions. Computer programs are able to perform this translation quickly, and the results can then be applied as objective parameters for developing new musical creations. Software can assist with rapid, clear musical notation and realtime playback during the composing period as well as with subsequent complex harmonious orchestration. Songwriting is similarly facilitated and appropriate vocal keys, harmonies, and arrangements can be easily derived. 

Most people never move beyond playing with AQD as a simple toy (which is, of course, perfectly fine), but if you re ready to make serious music, what follows is vital. Again, as with the previous chapter, the musical ideas discussed here are simple and should be seen as an introduction to music theory in light of ACID technology. None of these concepts should be viewed as a rule that must be followed—but you can t break the rules unless you first understand them. You certainly don t need to be a musician to work with ACID, but some knowledge of musical notation is necessary to use ACID to its fullest potential.

Such is the case in the companion poems on musical instruments, which demonstrate a delight in music. Indeed, two poems in the collection are prefaced with simple musical notation. Here is the first half of Upon a Skilful Player on an Instrument (lix) ... 

Sir James Dewar was born in Kincardine, Scotland, on September 20, 1842, the son of an innkeeper. He attended local schools until he was ten when he suffered a serious case of rheumatic fever lasting two years. During this period he built a violin, and music remained a lifelong interest of his. In 1858 he entered the University of Edinburgh. There he studied physics and chemistry. Dewar, in an early display of his dexterity, developed a mechanical model of Alexander Crum Brown s graphic notation for organic compounds. This was sent to Friedrich Kekule in Ghent who then invited Dewar to spend some time in his laboratory. 

Virtually all NMR experiments can described in terms of a pulse sequence, which, as the name suggests, is a notation which describes the series of radiofrequency (rf) or field-gradient pulses used to manipulate nuclear spins and so tailor the experiment to provide the desired information. Over the years, a largely (although not completely) standard pictorial format has evolved for representing these sequences, not unlike the way a musical score is used to encode a symphony. As these crop up repeatedly throughout the text, the format and conventions used in this book deserve explanation. Only the definitions of the various... 

Brown, Andrew R. Computers in Music Education Amplifying Musicality. New York Routledge, 2007. This book presents an easily understood overview of music technology to teachers and students, including sections on notation software, MIDI files, and downloading music. 

Table III. - The transformation of data from the photoelectron spectrum of phosphabenzene into musical notes. Column 1 gives the measured ionization potentials in eV. Column 2 gives the successive differences of ionization potentials in Hz. These latter are rescaled into audible frequencies Vj (column 3) by using the scaling factor k. The frequency v i of the closest note in the even tempered scale is given in column 4. Column 5 gives the names of the notes in the international (CDEFGABC) or roman do re mi fa sol la si do) notations, the frequency of A3 la3) being assigned the value 440 Hz. Note durations (column 6) are taken proportional to the intensities of the peaks in the spectrum, the unit being the sixteenth.
