The interval from A to Bb is a minor 2nd, also called a half step.
the interval is a 3rd.
The interval from B-flat to D is a major third, regardless of the key.
B-flat to C-sharp is an augmented 2nd.
B-flat up to G is a major 6th. Or, B-flat down to G is a minor 3rd.
Going from b-flat and e-flat is equal to a perfect fourth interval, which is five semitones (or "half-steps").
augmented 5th, as e flat to b flat is a perfect 5th and b is a semitone above b flat, making the interval augmented
E flat consists of 3 flats, B flat, E flat and A flat. E flat to B flat would be a perfect 5th interval as B flat is in E flat major, but because your question was E flat to B, B is a semitone up from B flat, this would mean the interval becomes a semitone larger, and a semitone larger from a perfect interval is augmented. Therefore, the answer to your question is an augmented 5th. Hope this helps :)
the interval is a 3rd.
The interval from B-flat to D is a major third, regardless of the key.
E-flat up to B-natural is an augmented 5th.
B-flat to C-sharp is an augmented 2nd.
B-flat up to G is a major 6th. Or, B-flat down to G is a minor 3rd.
Bb to D is a major 3rd.
Going from b-flat and e-flat is equal to a perfect fourth interval, which is five semitones (or "half-steps").
Minor third
When counted in half steps, B lies between these two notes. It implies that the interval has two half steps. Hence the interval between B flat and C is one whole step, one tone.
The interval between B-flat and G is equal to a major 6th. Thus, if a song has been transposed from B-flat major to G major, it will be a major 6th higher.
