Intervals larger than an Octave

Hi All
Apologies for this question, theory is my weak spot.
What happens when an interval is larger than an Octave?
For example, I have a song I play where the bass part I came up with goes from an A on the 5th fret E on the string to a C# on the 6th fret of the G string, if I played the C# on the A string it would be a Major 3rd, played on the G string does it remain a Major 3rd or would the name of the interval be larger than an Octave and if so what would the name of this particular Interval be? Sorry for all the questions and thanks again
 
I tend to "keep things simple" and subtract the octave, so I think of "an octave and a fifth" as a fifth. Not quite correct, but works for me. In jazz theory, intervals greater than the octave have scale tone numbers, that's where they get all of those 9th, 11th, and 13th chords from. And of course, Hendrix used those chords in whole new ways in his stuff...

a major 3rd played in the next octave is technically a 10th
You'd use that term to explicitly indicate what octave the major 3rd is meant to be played in

In pop/jazz chord symbols the extensions are almost always some version of 9th, 11th, 13th
you almost never see 8th, 10th, 12th, 14th intervals indicated.
that's because jazz chord symbols are functional, not explicit:
the voiced octave of each tone is up to the player
and the 8th, 10th, 12th, & 14th are functionally the same as 1, 3, 5, 7.

Thanks for that last explanation about why we don't see "even" intervals >8 talked about - makes perfect sense finally! :thumbsup:
