for any melody ...

strict about it.
in general, melodies should be primarily stepwise, with a single,
definite high point or low point. effective melodies tend to progress slowly toward
the high or low point and then move back toward the starting pitch.

as you can see above, occasional leaps are okay...
why, I
SHHHH. let’s just move on.
but they come with a bunch of restrictions.
first, leaps should be no larger than a perfect fifth, with two exceptions: leaping by a
perfect octave, and leaping upward by a minor sixth. don’t do these very often, though!

second, for heaven’s sake, avoid the tritone! this interval (an augmented
fourth or diminished fifth) was actively avoided so consistently that
Fux and his pals called it the diabolus in musica... the “devil in music!”

leaping by a tritone is bad, but it’s also
important to avoid the tritone in other
ways... for example, this pattern, where
a tritone is outlined in the melodic line,
would be considered inappropriate.
third, leaps of a perfect fourth need to be preceded or followed by stepwise motion
in the opposite direction, to counterbalance the leap. and if a leap is larger than a
perfect fourth, it needs to be counterbalanced both before and after!

but the first one isn’t in the opposite direction.
lastly, don’t write three or more leaps in a row. You can write
two leaps in a row, but they need to outline a major or minor
triad . no diminished triads... they have tritones in them!
evil!
