sesquialtera

Sesquialtera or the equivalent Greek term hemiola, three in the time of two as variously used in music theory: Sesquialtera commonly describes a tempo proportion in mensural notation. Hemiola is more common for the temporary substitution of a 2+2+2 musical meter for 3+3.

Definitions (Senses and Subsenses) 1. Having the proportion of one and one half to one, bearing the ratio of three to two; mus. proporcioun ~, an interval of a fifth.

SESQUIALTERA: • A stop on the organ which combines two ranks of pipes which enhance the higher harmonics of the fundamental tone • The ratio of 3:2 which can be represented in music by the interval of a perfect fifth The work utilises the unique sound of the Sesquialtera stop from the outset and each section of the ...

rubato, (from Italian rubare, “to rob”), in music, subtle rhythmic manipulation and nuance in performance. For greater musical expression, the performer may stretch certain beats, measures, or phrases and compact others.

There are four types of proportion

• Direct Proportion.
• Inverse Proportion.
• Compound Proportion.
• Continued Proportion.

The following are the important properties of proportion:

• Addendo – If a : b = c : d, then a + c : b + d.
• Subtrahendo – If a : b = c : d, then a – c : b – d.
• Dividendo – If a : b = c : d, then a – b : b = c – d : d.
• Componendo – If a : b = c : d, then a + b : b = c+d : d.
• Alternendo – If a : b = c : d, then a : c = b: d.

Metric rhythm, which is common to many types of music, involves the subdivision of the measure into equal units marked by a pulse called the beat. The first beat of the measure is usually accented. See: METRONOME, NOTE, POLYPHONY. Metric rhythm may be isometric or multimetric.

Metric structure includes metre, tempo, and all rhythmic aspects that produce temporal regularity or structure, against which the foreground details or durational patterns of any piece of music are projected.

Contrametric rubato involves a solo melody moving in subtly or equally redistributed note values (sometimes with added notes) against a steady pulse in the accompaniment. Structural or agogic rubato involves the simultaneous retardation or acceleration of tempo of the entire performing body.

There are three types of proportions: direct, inverse, and joint. Direct proportion is a relationship between two variables where the ratio of one variable to the other is always the same. In other words, as one variable increases, so does the other, and vice versa.

A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)
