Music analysis

Musical analysis "is the means of answering directly the question 'How does it work?'."(Bent 1987, 5) The method employed to answer this question, and indeed exactly what is meant by the question, differs from analyst to analyst, and according to the purpose of the analysis. According to Ian Bent (1987, 6), "its emergence as an approach and method can be traced back to the 1750s. However it existed as a scholarly tool, albeit an auxiliary one, from the Middle Ages onwards." Adolf Bernhard Marx was influential in formalising concepts about composition and music understanding towards the second half of the 19th century (Pederson 2001).

The principle of analysis has been variously criticized, especially by composers, such as Edgard Varèse's claim that, "to explain by means of [analysis] is to decompose, to mutilate the spirit of a work" (quoted in Bernard 1981, 1).

Some analysts, such as Donald Francis Tovey (whose Essays in Musical Analysis are among the most accessible musical analyses) have presented their analyses in prose. Others, such as Hans Keller (who devised a technique he called Functional Analysis) used no prose commentary at all in some of their work.

There have been many notable analysts other than Tovey and Keller. One of the best known and most influential was Heinrich Schenker, who developed Schenkerian analysis, a method that seeks to describe all tonal classical works as elaborations ("prolongations") of a simple contrapuntal sequence. Ernst Kurth coined the term of "developmental motif". Rudolph Réti is notable for tracing the development of small melodic motifs through a work, while Nicolas Ruwet's analysis amounts to a kind of musical semiology.
