(Redirected from Somatoform disorder). A somatic symptom disorder, formerly known as a somatoform disorder, is a category of mental disorder included in a number of diagnostic schemes of mental illness, including the DSM-5.
Piano uses all 10 fingers, and harp only uses 8. On piano, you have to understand more theory about when to use the black keys than you do on harp, which uses levers or pedals that often donât change through an entire song. Both instruments require you to use two hands to play two sets of notes.
The harp may therefore be well suited to the harmonious scale and in particular for use in sound/music therapy. The Sacred Chime [0089] FIG. 2 shows a musical instrument incorporating the Harmonious Scale in accordance to another embodiment of the present invention.
