Song duration and chart difficulty in RockClash
RockClash exposes duration and chart difficulty as separate song-creation settings. Duration requests the song length; difficulty targets the playable four-lane chart feel through easy, normal, hard or expert. A longer song is not automatically a harder chart, and a harder chart does not guarantee a higher score.

- Performance depends on the player and actual generated chart.
Choose for the intended session
Select a duration you are prepared to listen to and play-test, then choose a chart difficulty you can evaluate. Keeping these decisions separate makes it easier to understand whether feedback concerns the song or the beatmap.
- Set length for the intended use
- Choose a testable difficulty
- Do not infer density from duration alone
Validate after creation
Play the completed chart and inspect score, accuracy, combo and note grades. If the selected level is not readable for you, a different difficulty is a better comparison than judging the song solely from one failed run.
