How are intervals measured?
Intervals are counted by letter step (2nd, 3rd, 4th, etc.) and by quality (minor / major / perfect / diminished / augmented). Letter step + quality together pin the exact semitone distance.
How do I hear intervals from A♯ on Clarinet in A?
Each interval row has Ascending, Descending, and Harmonic play buttons. Start with Ascending to internalise the upper note's letter; switch to Harmonic to feel the consonance / dissonance against A♯.
Why is the tritone called the 'devil in music'?
Three whole tones (six semitones) bisect the octave exactly. The interval was avoided in early polyphony because its restless sound resists resolution. Today it's the defining tension in dominant 7th chords.
How do I train interval recognition?
Pair each interval with a familiar melodic fragment — perfect 5th = the first two notes of Twinkle, Twinkle; major 6th = the NBC chimes — then test yourself by playing intervals randomly from any tonic.
