frame of reference

"I had no frame of reference of what I was getting myself into," Lawrence, 28, told BBC Sport.

In terms of palate, I get my Chinese flare and frame of reference for ingredients in the kitchen from my father and his side of the family.

But in doing the research, I kept seeing cases like Wells’ critique, and that changed my entire frame of reference.

Hearing those comments "put me right back" in the recording studio, said Law, explaining that Britten's use of tonal ambiguity "didn't fit the normal frame of reference for a school choir".
