A Pianist
I had one English student whose other, well-known and well-pedigreed teacher insisted that one must ALWAYS play the bass AHEAD of the melody in, for instance a Chopin Nocturne, that this was accurate performance practice and crucial to the style. The effect was excrable!
What you are talking about is far more interesting and FAR less common in practice. In my experience, very few pianists even know about it. I myself know about it and use it (with discretion) because 1) I figured out for myself that it could be a Good Thing sonically, acoustically and interpretively, and 2) because I often noticed Horowitz doing it to excellent effect.
Constanly leading with the bass quickly bores, tiring the ear and lending a heaviness and rhythmic unsteadiness to the music. It tends to detract from musical tightness and vitality.
But leading with the melody capitalizes on a point of physics. If you voice one note louder than another on the piano, that voice's key descends more quickly and the note automatically sounds an instant or two ahead. This also helps it ring clearly - its attack is unblemishes by any other distractive sounds, and the bass is then 'snuck in' behind it. Further increasing the space between melody and bass adds a nice declamatory element to the rhetoric, and can be useful in pointing out an interesting harmonic turn.
Of course, overusing this is also going to lead to problems, but I find this technique possesses much more interesting potential than the other, far more widely and unconsciously used way of breaking the hands.
