Teaching support for teaching notions of musical harmony as part of its usein the instrumental play of accompanying instruments, in particular stringinstruments, and more especially the guitar, in which a couple of elementsare used which slide with respect to one another. These elements each carrycorrelated information. The first element is the outside element (1), whichcontains precise notions relative to a given harmonic tone and that is markedon the support. It has three openings that form windows (3a, 3b and 3c),which are preferably rectangular. The sliding element or inner slidecontains, correspondingly, precise information which provide theinstrumentalist with the possibility of acquiring, by co-ordinated slidingand reading through the open windows (3) precise data that is sufficient tocreate, in a given tone, a melody combined with a harmonisation, thecharacteristics of which, by playing the string instrument, are read in theopenings forming windows.
