A sequence of events is isochronous if the events occur regularly, or at equal time intervals. The term isochronous is used in several technical contexts, but usually refers to the primary subject maintaining a constant period or interval (the reciprocal of frequency), despite variations in other measurable factors in the same system.
Isochronous timing differs from synchronous timing, in that the latter refers to relative timing between two or more sequences of events.
A balance spring, or hairspring, is a spring attached to the balance wheel in mechanical timepieces. It causes the balance wheel to oscillate with a resonant frequency when the timepiece is running, which controls the speed at which the wheels of the timepiece turn, and thus the rate of movement of the hands. A regulator lever is often fitted, which can be used to alter the free length of the spring and thereby adjust the rate of the timepiece.
The balance spring is a fine spiral or helical torsion spring used in mechanical watches, alarm clocks, kitchen timers, marine chronometers, and other timekeeping mechanisms to control the rate of oscillation of the balance wheel. The balance spring is an essential adjunct to the balance wheel, causing it to oscillate back and forth. The balance spring and balance wheel together form a harmonic oscillator, which oscillates with a precise period or "beat" resisting external disturbances, and is responsible for timekeeping accuracy.
Isochronous is a rock band from Pretoria, South Africa. The group was formed in November 2006 by members Richard Brokensha, Marko Benini, Franco Schoeman and Alex Parker.
Their first studio album, Isochronous was released in September 2008 and distributed by Sony BMG in South Africa. Their second album, Imago was released in May 2010 independently.
Since 2007 the band has toured South Africa extensively, playing at a variety of major music festivals including Oppikoppi and RAMfest in 2010, where they shared the stage with international act Pendulum.
In September 2010 the band was invited by German star Marius Müller-Westernhagen to be his support act on his 10 show stadium tour of Germany scheduled for October 2010. While on this tour, the group performed at the O2 World (Berlin), Festhalle Frankfurt, O2 World (Hamburg), the Olympiahalle in Munich and the Lanxess Arena in Köln.
Their third studio album, Inscape, was released in 2011. Recording for their fourth studio album started in January 2012. The album will be recorded, mixed and mastered by the band and is due for release in mid-2012.
