Since C to F is a perfect fourth (5 semitones), C to F# would be an augmented fourth (6 semitones). F to B is also an augmented fourth (since F to Bb is a perfect fourth). Major intervals can be augmented by adding a half step.

What is the interval between the notes C and F?
For example, the notes C and D are two letter notes apart and so is an interval of a 2nd. But if we look at the notes C and E they are three letter notes apart and so this interval is a 3rd. The notes C to F are four letter notes apart and so would be a 4th.
What interval is C sharp to F?
4th intervals above note C-sharp
| Short | Medium | Intervals 'above' statement |
|---|---|---|
| d4 | dim4 | The C# to F interval is diminished 4th |
| P4 | perf4 | The C# to F# interval is perfect 4th |
| A4 | aug4 | The C# to F## interval is augmented 4th |
What is the interval A to F?
The interval between A and F is a sixth. Note that, at this stage, key signature, clef, and accidentals do not matter at all. The simple intervals are one octave or smaller. If you like you can listen to each interval as written in Figure 4.34: prime, second, third, fourth, fifth, sixth, seventh, octave.
