Swell

Draw how a phrase grows and fades — crescendos, hairpins and accents — to trace the target dynamics curve.

How to play

Each round gives you a target dynamics shape: a crescendo, a hairpin, terraced levels or a sudden accent. You draw your own loudness envelope across the phrase, then submit. The closer your curve hugs the target, the higher you score. You can hear both the target and your version before committing.

• Drag to draw the loudness rising and falling across the phrase
• Match the target's swells, fades and accents
• Hear the target and your own envelope to compare
• Submit when your shape lines up with the goal

Controls

• Desktop: click and drag on the canvas to draw the envelope; use Clear, Play and Submit
• Phone & tablet: drag your finger across the canvas to shape the curve

Game modes

• Daily: the same target shape for everyone each day
• Practice: a new dynamics shape every run

Tips & strategy

• Place the peak first, then ease the slopes in and out of it
• For a hairpin keep the rise and fall symmetric
• Listen back: your ear catches a mismatched accent faster than your eye
