To repeat section A in iRealPro, place repeat bar lines (: around it for playback. Specify repeat count with text in the last measure (e.g., 2x) or set it in Player options. Nested repeats within A are possible using additional bar lines and text instructions. Maximum repeat count is 30x per section. For advanced repeats or complex structures, consider using DS, DC, or coda symbols with segno markers. Good luck!
