The main theme from Interstellar by Hans Zimmer is one of the most popular kalimba melodies — and arguably the best choice for your first song. The slow, repeating organ figures turn into a calm walk across neighbouring tines, with no big jumps or tricky patterns.

The melody fits a standard 17-key kalimba in C completely, so no transposition is needed. Start in Listen mode to catch the pulse, then switch to Learn: the player waits for every correct note, and the whole theme comes together in a couple of evenings. Two-note chords appear closer to the middle — if they feel hard, just play the top note for now.
