How do you play easy and short songs on piano in letters?

To play easy and short songs on the piano using letters, first, find the song's melody and break it down into its individual notes. Each note corresponds to a letter: C, D, E, F, G, A, and B. You can write the melody in letter format (e.g., C E D C) to guide your playing. Practice playing these letters in sequence on the piano, matching them to the correct keys.
