intervals

An interval of a second would be the distance of two frets on the same string right? So when writing this on a staff if going from the B line to the C space you would have to write C# right? Or if you had a fourth or an octive or something which went over the b and c or e and f you would have to make the last note sharp to make up for the half step right?

Right.

Right, from the B to the C# is a second or a whole step (i.e.: two fret apart on the same string).

Not necessarily. You just have to be careful about your starting note, your interval & how it works out on the staff.

From B on the middle staff line up a 4th to E puts you on the top space. But from B on the middle staff line up a 5th to the F# means you have an F on the to line, but you have to add a sharp in order to indicate F#.

But octaves are by definition the same note simply up higher or lower. So B is B an octave higher. It is interesting on the staff that from octave to octave you alternate from line to space back to line to space, and so on.

You do not automatically add a sharp to every or any given interval crossing the staff. You just have to get used to the idea of intervals applied to musical alphabet letters with accidentals. Then you apply that to the staff.

Make sense?

I think so. Thanks
