Which is the smallest possible interval in music?
Semitones and tones or half steps and whole steps, are the building blocks of intervals. We use different combinations of them to make up all the different types of scales and chords that make music sound so different.

Are there any intervals that are the same note?
We can also have intervals that are the same note. For example, two different instruments might play exactly the same note in a piece of music. This interval is called a unison. When we write a harmonic unison interval (more on harmonic and melodic intervals shortly) we write the notes next to each other.
