Understanding Interval Relationships on Your Piano / Keyboard
The diagram below shows the C note on the bottom. Every other note has a certain distance from the C note. That distance is an interval. The exact distance has different names. Look at the F note; it is the major fourth because it is the fourth note apart of the C major scale. You would count C as 1, D2, E3, and F is the fourth (4). If you heard the notes C and F played back to back, the interval difference between the two notes is a major fourth. When you hear two notes played, it is almost impossible to know the exact note that it is. For example, most people cannot hear a tone and immediately know that is a Bb (flat). However, when you hear notes played, it is possible to figure out the distance between those notes. You could hear single notes played back to back or two notes played together.
