The musical structure of the Malu Prelude is a reproduction of the single-tripartite structure, consisting of three sections. The first section consists of two phrases, starting in the key of D major. The two phrases have similar musical materials, each of eight measures, and both end on the main chord of D major. Therefore, this section has a square structure, parallel material, and a converging section.

1. The second section consists of two phrases. The two phrases have similar musical materials and are eight measures each. The first phrase ends with the tonic chord of A major, and the second phrase ends with the dominant chord of D major, ending with Looking forward to reappearing. Therefore, this section has a square structure, parallel material, and an open section with modulation.

2. The third section reproduces the content of the first section. It consists of two phrases, each with eight bars, both ending in the main chord of D major.
