In small-atom solids such as dense metals, the sound can travel at much higher frequencies due to both higher sound speed and the periodicity and strength of the lattice. Theoretically, an alien civilization with their "ears" designed to hear through solids rather than gases would be able to make music with these higher frequencies, and perceive intervals as distinct instead of "wahwah". | In small-atom solids such as dense metals, the sound can travel at much higher frequencies due to both higher sound speed and the periodicity and strength of the lattice.
