Modest amounts of second harmonic distortion are perceived as "warmth."
There are even EFX generators that contain a second harmonic generator,
and the control for it is called "warmth." When left to their own listening
judgement, a recording engineer will usually choose a setting on the order of
a few percent.
In general, the lower the order of the distortion, the closer it comes to
with musical harmonic intervals, and the higher the order, the more
dissonant. Tubes tend to be higher in low order harmonics and lower in high
order harmonics. In other words, tubes clip more gracefully than transistors.
