Brand: Well Tempered
The "Well-Tempered Clavier" is a famous collection of two volumes of piano preludes and fugues composed by Johann Sebastian Bach. The term "Well Tempered" refers to the system of Tuning in which the keys are arranged so that they are all useable and tonally related, as opposed to old methods where some keys were considered "tempered" (sharper or flatter than standard) in order to improve the consonance between specific key signatures. The "Reference" in this context refers to the authority and standard-setting nature of Bach's music in the classical repertoire, which has served as a basis for later composers and musicians to study, learn, and build upon.
