Music is the art of sound. From an objective standpoint, there is no good music or bad music, no happy music or sad music. However, music can be subjectively evaluated. Is it pleasing to listen to? Does it inspire the ideas and emotions the composer/performer sought to communicate? Thus, there are good musicians and bad ones. Good ones understand that sound has objective properties, knows how to manipulate these properties, and puts this knowledge into action. The composer must know way more than I can cover here. The performer must be able to play understand his instrument and play with the desired techniquepurpose and direction.
