Danny, while writing my last answer, I thought of tones and fifths, since
this interval was mentionned in a sentence I will quote just lower.
But then I remembered a very long thread about overtones, in which people
were disagreeing about their im****tance in music theory, and thus I
censored
my own message ;-)

I strongly disagree with this sentence (which wasn't yours, IIRC).
I think "a leap" contains the idea of jumping over something, or skipping
something - as LJS has just said in a recent message.
Going from a note to its neighbour, and calling that a leap, is really
more
than I can admit :-o
(whatever the distance between these two neighbours - that's why I tried
to build this strange scale)
In C major the smallest interval is a semitone ; will we say it's a leap,
just because some other scales may contain quarter tones ? Of course not.
If a scale contains tones only, we won't either call a leap a transition
from
a note to its neighbour.
Then, when a scale doesn't contain any tone or smaller interval, why would
we suddendly call a leap a transition from a note to its neighbour ?
