Sonolus

Install and open Sonolus, then add a community server or browse featured sources to download songs, charts, and skins. Calibrate audio and input offsets and set frame rate to achieve smooth visuals and accurate timing. Select a song and difficulty, preview the chart, and configure mods such as note speed and visual effects. Play to the beat by tapping, holding, sliding, and flicking as cues reach the hit line to build accuracy and combo. Practice difficult sections using slower speed or quick-retry to refine timing and push for higher grades. Customize your experience with different skins, effects, and rulesets, then replay songs to improve personal bests and compare scores where available.
