Hello, this is the kind of music that appeals to me most. It needs to have a central idea, and the melody should be progressive; percussion serves merely to support the climax or to introduce variations and melodic shifts. You typically discover a melody that you then repeat throughout the piece in different ways and with various instruments. The beginning, development, and ending are all important—everything must aim to convey that core idea. The listener perceives not just the melody, but also the artist's personal touch; if you feel emotion while creating your tracks, then the listener is likely to feel it too. Best regards.
