Playing Mozart like Mozart
Everything in this stage — vibrato, rubato, the agogic accent, tone colour — plus Stage 6's slides and Stage 3's articulation, comes down to one question when you sit down with a real piece: how much of each? And the answer depends almost entirely on when the music was written.
The two settings
| Dial | Classical (Mozart, Haydn) | Romantic (Bruch, Tchaikovsky, Kreisler) |
|---|---|---|
| Vibrato | narrow, selective — an ornament on chosen notes | wide, warm, continuous |
| Slides / portamento | essentially off | expressive, frequent |
| Rubato | tiny, structural — a breath, never a wilful slowing | generous, audible ebb and flow |
| Articulation | non-legato is the default; slurs are the marked exception | long legato lines are the default |
| Dynamics | contained, speech-like, terraced; the Classical Allegro is restrained | broad swells, extremes |
| Tone | clear, transparent, light | thick, rich, projected |
Play a Mozart phrase with the right-hand column and it will sound wrong even though every note is correct — too heavy, too slow, too smeared. This is the same rule Stage 3 gave you for every symbol on the page: the mark tells you what; the era tells you how. It's just that here the "marks" are your own expressive choices.
One phrase, two styles
How to play it
For the Classical version keep the bow lighter and let tiny spaces open between the separate notes; save the vibrato for the two long notes. For the Romantic version, one long connected line, vibrato throughout, lean into bar 3.
Restraint is not the absence of expression
The Classical column is restrained, not dead. A Mozart slow movement is deeply expressive — but its expression is in the shape of the line, the placement of a single agogic lean, one perfectly-judged narrow vibrato on an arrival note. It's a whisper doing the work of a shout. Playing Mozart dry and clipped, with no shaping at all, is as wrong as drowning him in vibrato.
Try it
Try
Take the phrase above, or any phrase you know. Play it "Romantic" — everything full, wide, connected, free. Then play it "Classical" — light, narrow, spoken, contained but still shaped. Name out loud the five things you changed. That list is the difference between playing Mozart and playing him like Brahms.
The usual mistake
Applying one modern "expressive default" — continuous wide vibrato, generous rubato, everything slurred — to every piece regardless of era, so Mozart comes out sounding like a film score. The over-correction is just as wrong: playing Classical music so austere and metronomic that it has no life. The target is shaped restraint.
