“…The results of these works were summarized in a review conducted by Maria Dymnikova. Having analysed a number of music therapy reports, the author concluded that positive effects tended to be linked to the following factors: (1) String instruments are to be applied or, wind instruments with high acoustic sound frequencies, (2) Music is to be well-ordered in temperament, in modality (minor and major), modulation which is not to be irritating for the ear, (3) Voices are to be linked to one another in a polyphonic way, or as a homophonic melody, accompanied by bass, (4) Melodic phrases are to be divided into either four-or eight-tact periods, (5) Rhythm (agogics) is to correspond to human physiological rhythms, such as heart rate, brain rhythms, breathing cycles, (this regularity is proper for the second (slow) part of a number of instrumental concerts of the Baroque art and of the early Classicism), (6) Volume is to be in the lower part of the volume register (with a range of up to 50 dB), with volume changes occurring gradually and within the aforementioned volume range (Dymnikova, 2016). All of these properties apply to the music by Mozart and other "old classics" composed before 1790,and to a number of later compositions, like "Clair de Lune" (Moonlight) by Claude Debussy.…”
