In this game you will hear two notes, one after the other in ascending order. The notes will be anywhere from a minor 2nd apart (1 semitone) up to a perfect octave. You can select the range of intervals below, and choose whether they all begin from the same root note, or from a random root note. Press R to replay, and Space for 'Next'.

Intervals describe the distance between two distinct pitches, and are measured in semitones (half-steps for all you North Americans). The smallest interval is the Perfect Unison, which would be two of the exact same note - think two 'Middle C's' on two pianos. Two notes a single semitone apart have the interval of a Minor 2nd, commonly written 'm2'. An interval of 2 semitones (more commonly called just a 'tone', or a whole-step again for our US and Canadian friends) is called a Major 3rd, or a 'M3' interval. This game plays intervals from a Minor 2nd (m2) up to a Perfect Octave (P8). Learning the sound of different intervals can be beautifully useful as we use intervals to construct other musical elements, such as chords. A nice example of this would be the Major triad, which takes a root note, ie 'C', adds a Major 3rd interval which in this case takes us up to 'E', and then a further Minor 3rd which in this example brings us up to 'G'. Therefore the C Major triad is the notes C, E and G.
