Algebra and Geometry in Music?<\/strong>
\nThe mathematical foundations of music involve algebra and geometry, in a complex relationship that has been known for thousands of years.\u00a0 Ancient mathematicians from China to Greece were interested in the relationship between music, nature, and numbers.\u00a0 The acoustics of sound show the mathematical relationships that underlie pitch, loudness, and the musical scale itself.<\/p>\n

Rhythm, Meter, and Tempo<\/strong>
\nThe patterns of rhythm and tempo are measured very precisely in music.\u00a0 They can be expressed in ratios, counting, and number patterns.\u00a0 Most musicians become very familiar with the duration of notes and the ratios between them.\u00a0 For example, in any time signature whole notes are held for a certain number of beats and all other notes are a fraction of them.\u00a0 In order for different parts to produce harmony, the relationships between \u00a0them must be coordinated so that each note is played or sung for a specific length of time.<\/p>\n

Scales and Harmonics<\/strong>
\nPitches are heard and produced because the part of the instrument that is producing the note vibrates at a certain frequency. Every scale of music, whether the pentatonic scale found in Asian music, to the diatonic scale of Western music, to the tone row of modern classical music, uses particular frequencies that are multiples of lower frequencies.\u00a0 Tones sound like they are in harmony because the ratios harmonize.<\/p>\n

Plato and Pythagoras<\/strong>
\nPlato was fascinated by beauty and nature and saw harmony in terms of mathematical precision.\u00a0 Pythagoras, who developed many of the mathematical concepts in geometry, showed the geometric relationships between musical notes.\u00a0 Ancient Greek music was based upon modes of note arrangement, with relationships fixed in specific patterns of intervals.\u00a0 (We know because many of those ancient modes of music survived and found their way into Western music.)<\/p>\n

Well-Tempered Scales<\/strong>
\nWestern music developed as it did because of a mathematical innovation.\u00a0 In any octave, there are exactly 12 half-steps.\u00a0 \u00a0For an instrument, such as a piano, to play in all the different keys, those 12 half-steps must have exactly the same interval between two notes next to each other.\u00a0 This process is called a “tempered” scale, which Bach demonstrated in The Well-Tempered Clavier<\/em>.\u00a0 He composed preludes and fugues in each key to show how the process of tempering worked.<\/p>\n
