The interval from B to C is a minor second (m2) or a half step.
Whole step or half step
Octave
The musical interval between two notes depends on the ratio of their frequencies. An octave is a ratio of 2:1 and, in equal temperament comprises 12 equal semitones, which therefore have a ratio of 21/12.
An interval of eight notes is known as an octave.
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 :)
On the piano, if one plays B-sharp the heard note is C-natural. Conversely if one plays C-flat, the heard note is B-natural. For the same reasons the interval between E and F is also a half step. A musical scale can have only 12 semi-tones (half-steps).
Minor third
Interval notation uses the symbols [ and ( to indicate closed an open intervals. The symbols can be mixed so that an interval can be open on one side and close on the other. Given two real numbers, a, b we can have (a,b) which is the interval notation for all numbers between a and b not including either one. [a,b) all numbers between a and b including a, but not b. (a,b] all numbers between a and b including b, but not a. [a,b] all number between a and b including a and b.
There is more than one notation, but the open interval between a and b is often written (a,b) and the closed interval is written [a,b] where a and b are real numbers. Intervals may be half open or half closed as well such as [a,b) or (a,b]. For all real numbers, it is (-infinity,+infinity), bit use the infinity symbol instead (an 8 on its side).
Interval means only ONE Thing : The Distance BETWEEN notes or tones. Like a scale degree. eg: tonic, supertonic, subdominant.....
An augmented seventh is a musical interval spanning seven note names and 12 semitones - for example, C to B sharp.
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 is a 3rd.
Octave
If the function is continuous in the interval [a,b] where f(a)*f(b) < 0 (f(x) changes sign ) , then there must be a point c in the interval a<c<b such that f(c) = 0 . In other words , continuous function f in the interval [a,b] receives all all values between f(a) and f(b)
a musical interval composed of three adjacent whole tones.
