## What is Interval?

Interval turns scattered music theory drills into a measurable practice habit. Whether you're prepping for a theory exam, returning to an instrument, or sharpening your ear, Interval gives you fast, focused exercises with instant feedback, mastery tracking, and a clean, modern interface — no subscriptions, no account, fully offline.

WHAT YOU CAN PRACTICE
• Interval identification — read two-note intervals and name them
• Scale identification — major, minor, modes, pentatonic, and more
• Chord identification — triad and seventh-chord qualities
• Keyboard exercises — tap the piano to answer, or name highlighted keys
• Ear training — interval, chord, and scale recognition by sound

BUILT FOR REAL PROGRESS
• Mastery rings for every skill so you always know where you stand
• Session summaries that show exactly what you missed
• Per-skill stats and accuracy trends over time

DESIGNED TO BE FAST AND FOCUSED
• Procedurally generated exercises — practice never runs out
• Multiple-choice and tap-the-piano answers
• Instant grading with gentle haptics and optional auto-advance
