Interval Calculator

The Interval Calculator is a comprehensive music theory tool that determines the exact interval between any two selected notes, displaying the interval name, semitone count, and detailed harmonic analysis including consonance/dissonance levels and acoustic properties. Users simply select a starting note and destination note to instantly see results with musical context, famous song examples that use that interval, and frequency ratio information based on just intonation and harmonic series principles. The tool includes educational features like interval quality classifications (perfect, major, minor), real-world musical examples from classical and popular music, and a quick reference chart of all twelve intervals, making it perfect for music students learning interval recognition, composers analyzing harmonic relationships, or musicians developing their ear training skills.
