Your Lie in April

The Your Lie in April watch order is essentially all 22 episodes followed by one OVA, making it an easy franchise to complete in full. Watch Episodes 1-22 first, the complete A-1 Pictures adaptation that follows Kousei's return to the piano through Kaori, and only then watch the Moments OVA. That side story is a recap-style companion piece, so it belongs after the series rather than woven into it, and viewing it last preserves the emotional weight of the finale. There are no movies or additional seasons to worry about, which makes this the correct order by default: the main run, then the OVA. If you want the complete experience including the OVA, this is the sequence to follow, and it keeps everything in proper order without any optional installments to hunt down separately.
