Correlative comparison (nu atât... cât)

To downplay one quality and emphasize another, Romanian uses the correlative structure nu atât..., cât.... This translates directly to "not so much... as...".

The new album is not so much banal, as repetitive.
Noul album nu este atât banal, cât repetitiv.
We liked not so much the production, as the originality.
Ne-a plăcut nu atât producția, cât originalitatea.

Whatever grammatical form follows nu atât (an adjective, noun, or phrase), a matching form should follow cât.

Adding Emphasis with "Mai ales"

To place even stronger emphasis on your preference, insert mai ales (especially) immediately after cât.

We appreciated not so much the voice, as especially the instrumental.
Am apreciat nu atât vocea, cât mai ales instrumentalul.
The critic praised not so much the instrumental, as especially the originality of the composition.
Criticul a lăudat nu atât instrumentalul, cât mai ales originalitatea compoziției.

Matching Prepositions

If the first contrasted item uses a preposition (like prin or pentru), repeat that preposition after cât (or cât mai ales) to keep the sentence balanced.

The band moved us not so much through the rhythm, as through the expressive lyrics.
Trupa ne-a emoționat nu atât prin ritm, cât prin versurile expresive.
The fans bought the album not so much for the production, as especially for the message.
