The Oxford Companion to Music defines music criticism as 'the intellectual activity of formulating judgments on the value and degree of excellence of individual works of music, or whole groups or genres'. In this sense it is a branch of musical aesthetics. With the concurrent expansion of interest in music and information media over the past century, the term has come to acquire the conventional meaning of journalistic reporting on musical performances. (See music journalism).
Nature of music criticism 
The musicologist Winton Dean has suggested that music is probably the most difficult of the arts to criticize." Unlike the plastic or literary arts, the 'language' of music does not specifically relate to human sensory experience - Dean's words, "the word 'love' is common coin in life and literature: the note C has nothing to do with breakfast or railway journeys or marital harmony." Like dramatic art, music is recreated at every performance, and criticism may therefore be directed both at the text (musical score) and the performance. More specifically, as music has a temporal dimension that requires repretition or development of its material "problems of balance, contrast, expectation and fulfilment ... are more central to music than to other arts, supported as these are by verbal or representational content." The absence of a clearly evolved or consensual musical aesthetics has also tended to make music criticism a highly subjective issue. "There is no counter-check outside the critic's own personality".
To end of 18th century 
According to Richard Taruskin, the active concert life of late 18th-century London meant that "the role and the function of arts criticism as we know it today were the creations of the English public." However the first magazines specifically devoted to music criticism seem to have developed in Germany, for example Georg Philipp Telemann's Der getreue Music-Meister (1728), which included publications of new compositions, and Der critische Musikus which appeared in Hamburg between 1737 and 1740. In France in the 1750s, the Querelle des Bouffons, (the dispute between supporters of French and Italian opera styles as represented by Jean-Philippe Rameau and Jean-Baptiste Lully respectively), generated essays from Jean-Jacques Rousseau and others, including Denis Diderot's Rameau's Nephew (1761). The English composer Charles Avison (1709–1770) published the first work on musical criticism in the English language - an Essay on Musical Expression published in 1752. In it, Avison claims that since the time of Palestrina and Raphael, music had improved in status whilst pictorial art had declined However he believes that George Frideric Handel is too much concerned with naturalistic imitation than with expression, and criticises the habit, in Italian operas, of
'that egregious absurdity of repeating, and finishing many songs with the first part; when it often happens, after the passions of anger and revenge have been sufficiently expressed, that reconcilement and love are the subjects of the second, and, therefore, should conclude the performance.'
Typically until the late eighteenth century music criticism centred on vocal rather than instrumental music - "vocal music ... was the apex of [the] aesthetic hierarchy. One knew what music was expressing."
Age of Romanticism 
The last years of the eighteenth century reflected both a change of patronage of music from the aristocracy to the rising middle-classes and the rise of Romanticism in the arts. Both of these had consequences for the practice of music criticism; "the tone of the critic was lowered as his audience expanded: he began to approach the reader as a colleague rather than a pedagogue", and a new generation of critics began to widen their consideration to other aspects of music than its pure representative aspects, becoming increasingly interested in instrumental music. Prominent amongst these was E. T. A. Hoffmann, who wrote in 1809
That instrumental music has now risen to a level of which one probably had no inkling not long ago, and that the symphony, especially following...Haydn and Mozart, has become the ultimate form of instrumental music - the opera of instruments, as it were - all this is well-known to every music-lover.
A further impetus to the direction of music criticism was given by the changing nature of concert programming with the establishment of the European classical music canon; indeed it is at this peariod that word 'classical' is first applied to a received musical tradition. At the same time the proportion of new music to 'canonic' music in concert programming began to decline, meaning that living composers were increasingly in competition with their dead predecessors. This was particularly the case in respect of the rise of Beethoven's reputation in his last year and posthumously. This gave rise both to writings on the value of the 'canon' and also to writings by composers and their supporters defending newer music.
In 1798 the Allgemeine musikalische Zeitung, edited by Friedrich Rochlitz (1769-1842) began publication in Leipzig, and this is often regarded as the precursor of a new genre of criticism aimed at a wider readership than qualified connoisseurs. In subsequent years a number of regular journals decidcated to music criticism and reviews began to appear in major European centres, including the The Harmonicon, (London 1823-33), the Musical Times (London, 1844-date), the Revue et gazette musicale de Paris (Paris 1827-1880, founded by François-Joseph Fétis), the Berliner allgemeine musikalische Zeitung founded in 1825 by A.M. Schlesinger and edited by A. B. Marx, and the Neue Zeitschrift für Musik founded in 1834 in Leipzig by Robert Schumann and Friedrich Wieck, and later edited by Franz Brendel. Other journals at this period also began to carry extensive writings on music: Hector Berlioz wrote for the Parisian Journal des débats, Heinrich Heine reported on music and literature in Paris for the Stuttgart Allgemeine Zeitung, the young Richard Wagner wrote articles for Heinrich Laube's magazine Zeitung für die elegante Welt and during his 1839-42 stay in Paris for Schlesinger's publishing house and for German newspapers. In 1835 J.W.Davison (1813–85) began his lifelong career as a music critic, for forty influential years of which he wrote for The Times.
