What are the parameters of music to consider so that the resulting composition is suitable as a background music when reading, studying or doing some mental work?
I'm interested in parameters like tempo, rhythm, instruments, elements of music supporting concentration and make the book more colorful (compare it to speech and intonation or using more voices in educational tapes). Are there some music patterns releasing stress, some happy vibrations that should be added? What else should I consider in composition of such a music?
I was looking for some sources but found only sources without scientific (bibliographical) references dealing with similar topic (influence of music on learning). Read the paragraph beginning with "Baroque 17th & 18th century".
