Apart from the discrete dynamic shaping of phrases [ it is understood this means all parts, not just the prominent melodic / motivic elements ], what many a pianist misses are the Luftpausen, the little bits of 'airspace' between the end of a phrase and the beginning of a new phrase. The principle is 'halfway' true for those half-way points where a complete break is not indicated or desired.
Luftpuase: German (from wikipedia): '
"A breath mark or luftpause or, for bowed instruments, a bow lift, is a symbol used in musical notation. It directs the performer of the music passage to take a breath (for wind instruments and vocalists) or to make a slight pause (for non-wind instruments). For bowed instruments, it means to lift the bow. This pause is normally intended to affect the duration of the preceding note and not the tempo. It is usually placed above the staff and at the ends of phrases. Its function is analogous to the comma in several written languages. Indeed, the two symbols look identical."
There you are. you shave a bit of length off the end note of phrases (keeping in tempo). The finger technically rounding-off or 'finishing' the note, via touch or how the note is released, is the rest of the effect. When executed, this can be heard whether the damper pedal is down or off. It makes a subtle and huge difference.
I would bet if your playing is not dynamically flat, this is the area you should be looking into.
You can try, with a midi editor, playing something and quantizing it to the clock, and make the note lengths all full-duration ( even better if it is running sixteenths or some steady numeric configuration.) With the editor, shorten the length of the last note of a phrase ~ just a few digits ~ and leave the rest as quantized and with the full durations. Play it back: you will demonstratedly hear how much a tiny Luftpause can affect what we hear.
This is what Arthur Schnabel was speaking of in this famous quote,
"The notes I handle no better than many pianists. But the pauses between the notes—ah, that is where the art resides."
Ironically, this means what to Not Play!
Of course, armed anew with this thought, you will consult with your teacher, right?
