A rust canyon, two cliff ledges, and a rope whose width is the interval you hear. Hear two tones, drag the climber onto the matching rope, then Leap. A small gap is an m2. A wide gap is a P8. Board the far ledge for Score and a Streak. A wrong rope is a Fall into the shade.
Pick a canyon
Tap Easy, Medium, or Hard. Then Leap in. Lives start at three. Eight Spans reach Far ledge.
Hear the interval
Two tones play. Hear plays them again. A close pair is a small span. A wide pair is a long rope.
Drag, then Leap
Drag the climber onto the rope whose width matches what you heard. Press Leap. Space also Leaps.
Board or Fall
The matching rope is Boarded! with dust and Score. A wrong length is a Fall into the shade and resets the Streak. Chase a new Best.
Physical distance is ear distance
The gap width maps to the interval. An m2 is a short rope. A P5 is longer. A P8 is the wide span. No labeled interval buttons — you Leap by how far it sounds.
Drag, then Leap
Drag the climber onto a rope. It snaps to a bridge length. Press Leap. Hear plays the two tones again. Boarded! puffs dust on the far ledge. Fall! drops you into the shade.
Score, Streak, Spans
Each Boarded! adds Score and grows the Streak. Eight Spans reach Far ledge. Three Falls close the canyon. Point pops fly off a hit.
Difficulty that changes the ear
Easy is m2 / P5 / P8 on slow ropes. Medium is m3 M3 P4 P5 — closer widths. Hard uses all diatonic intervals and plays them faster.
Span Leap is a middle-school pitch game. A climber stands on a rust canyon ledge. An interval plays — two tones. The player drags the climber onto a rope-bridge whose width maps to that interval, then Leaps. Physical distance is ear distance: m2 is short, P8 is wide. A hit boards the far ledge. A miss is a Fall into the shade. Easy uses m2 / P5 / P8. Hard opens all diatonic intervals and plays them faster.
Intervals as space
Kids feel a P5 as a longer rope than an m2. That is closer to hearing size than tapping a named card.
Hear, then Leap
The verb is Leap. Hear replays the pair. Boarded! and Fall! change the canyon, not a green label.
Skill changes with difficulty
Easy stays on three far-apart spans. Medium packs m3 M3 P4 P5. Hard asks every diatonic interval at a faster Hear.
Score that plays
Score, Streak, and Spans sit on rust plaques. A Streak grows the next Boarded! pop.
Drag the climber onto a rope so it snaps to a bridge length. Press Leap, or the space bar. Hear plays the interval again.
A short rope is a small interval such as m2. A wide rope is a P8. The gap width maps to what you hear.
The climber drops into the shade and you lose a life. The Streak resets. Three Falls are Canyon closed.
The interval set and how fast the two tones play. Easy is m2 / P5 / P8. Medium is m3 M3 P4 P5. Hard is all diatonic intervals, faster.
Sixth through eighth grade (middle school), when students name and hear intervals. Stay on Easy to learn the three far-apart spans.
