In the classical period, the theme consists of phrases with contrasting melodic figures and rhythms. These phrases are relatively brief, typically four bars in length, and can occasionally seem sparse or terse. The texture is mainly homophonic, with a clear melody above a subordinate chordal accompaniment, for instance an Alberti bass. This contrasts with the practice in Baroque music, where a piece or movement would typically have only one musical subject, which would then be worked out in a number of voices according to the principles of counterpoint, while maintaining a consistent rhythm or metre throughout. As a result, Classical music tends to have a lighter, clearer texture than the Baroque. The classical style draws on the "style galant", a musical style which emphasised light elegance in place of the Baroque's dignified seriousness and impressive grandeur.
