Computers are used in the music field for generation of sound, for composing music, for analysis of music, and for musicological applications, such as cataloguing a bibliography of music literature. These areas are relatively new aspects of computer usage, and research is being conducted to stay abreast of current technological advancements. Avant-garde composers are challenged by new advances in music. Computer-generated music is one of the new trends, but the composer is usually limited in the use of the medium for two reasons: there are no computers to which he may have access, and/or there is not enough knowledge about computer-generated music. The composer sometimes feels that he must have vast knowledge of the computer before he can attempt to use it in musical composition; however, a limited amount of investigation of computer-generated music has shown that methods can be codified to the point where great technical knowledge is not required of the composer.

Some artists have been creating covers systematically and we can find their work in several publishers, but for some this activity was only a short episode in their work.

In some cases, this section also records the original illustrations stored in the Museum of Applied Arts in Prague, which were very helpful in identifying the artistic practices. It is clear from this diploma thesis that the illustrations of these sheet music, which have not been given space in the literature so far, are an important...
