Unison

In music, unison is two or more musical parts sounding the same pitch or at an octave interval, usually at the same time.

Rhythmic patterns which are homorhythmic are also called unison.

Interval of the unison

Unison or perfect unison (also called a prime, or perfect prime) may refer to the (pseudo-)interval formed by a tone and its duplication (in German, Unisono, Einklang, or Prime), for example C–C, as differentiated from the second, C–D, etc. In the unison the two pitches have the ratio of 1:1 or 0 half steps and zero cents. Although two tones in unison are considered to be the same pitch, they are still perceivable as coming from separate sources, whether played on instruments of a different type:  play unison on C, piano and guitar ; or of the same type:  play unison on C, two pianos . This is because a pair of tones in unison come from different locations and/or can have different "colors" (timbres), i.e. come from different musical instruments or human voices. Voices with different colors have, as sound waves, different waveforms. These waveforms have the same fundamental frequency but differ in the amplitudes of their higher harmonics. The unison is considered the most consonant interval while the near unison is considered the most dissonant. The unison is also the easiest interval to tune. The unison is abbreviated as P1.

UNISON

UNISON is the second largest trade union in the United Kingdom with almost 1.3 million members.

The union was formed in 1993 when three public sector trade unions, the National and Local Government Officers Association (NALGO), the National Union of Public Employees (NUPE) and the Confederation of Health Service Employees (COHSE) merged.

UNISON's current general secretary is Dave Prentis. He was elected on 28 February 2000 and took up the post on 1 January 2001, succeeding Rodney Bickerstaffe who had held the post for five years.

Members and organisation

Members of UNISON are typically from industries within the public sector and generally cover both full-time and part-time support and administrative staff. The majority of people joining UNISON would be workers within areas such as local government, education, the National Health Service Registered Nurses, NHS Managers & Clinical Support Workers. The union also admits ancillary staff such as Health Care Assistants and Assistant Practitioners, including Allied Health Professionals. Probation services, police services, utilities (such as gas, electricity and water), and transport. These 'Service Groups' all have their own national and regional democratic structures within UNISON's constitution.

Unison (video)

Unison is Celine Dion's first home video, released on VHS on July 2, 1991. It includes the music videos from her English debut album Unison.

Three videos: "Délivre-moi," "Have a Heart," and "Calling You" were filmed during the Unison Tour at the Winter Garden Theatre in Toronto, Canada, and later shown in the 1991 MusiMax TV special.

In the United States, the U.S. version of "(If There Was) Any Other Way" from 1991 was included; in Canada, the Canadian version from 1990. This VHS was made in both English and in French. The two contain similar interviews conducted in both languages.
