Vocal blend does not have to mean that two singers lose their identities. Joan Baez and Paul Simon’s “The Boxer” at her 75th birthday celebration offers a useful way to hear the distinction. A shared performance can retain recognizable differences while making those voices belong within one musical statement.
PBS identifies the celebration at New York’s Beacon Theatre in 2016. The related “Here Comes the Sun” selections then change the partnership, allowing the number and identity of singers to be considered separately from what their voices actually do.

Headcount does not describe the texture
Two people on stage can alternate, sing the same melodic line, or take different pitches at the same time. Those situations create different musical relationships even though the number of performers remains constant.
Begin with a short passage and identify how many vocal lines you can follow, rather than merely how many singers you can see. If the sound feels shared, consider whether that impression comes from a common melodic direction, similar timing, or different notes fitting together.
You do not need to name an exact interval to make a useful distinction. Describing a second voice as moving alongside the principal line is already more specific than calling every simultaneous passage a harmony without further attention.
A shared phrase has several boundaries
Blending concerns more than pitch. The beginning of a word, the continuation of its vowel, and the completion of its ending can all affect how a phrase is heard as a unit. Individual vocal colors may remain audible through that coordination.
Choose a phrase ending and listen beyond its strongest point. Follow how the sound settles and what happens before the next statement. This can reveal a relationship less immediately conspicuous than a large vocal entrance.
A produced recording also directs attention through balance. A voice that seems less prominent is not necessarily contributing less musical work; its role may be to define the shared sound around the featured line.
Three names, another division of attention
The “Here Comes the Sun” selection with Simon, David Crosby, and Graham Nash changes the composition and expands the named partnership. It offers another setting in which to distinguish visible people from audible functions.

Follow the principal melodic idea first, then listen for what surrounds it. A larger group can make the relationship between a tune and its supporting parts more apparent, but the comparison should remain tied to a passage you can actually identify.
Hold the song and reduce the pairing
Simon and George Harrison’s “Here Comes the Sun” supplies the final selection. The composition stays in place while the partnership changes again.

This creates a useful listening route: first hear the Baez–Simon duet on its own, then compare two different partnerships on another song. The second comparison helps prevent every perceived difference from being attributed only to repertoire.
Returning to “The Boxer,” the idea of blend can become more precise. It can describe coordinated timing and compatible musical roles without implying identical voices. Baez and Simon remain recognizable individuals, while the shared work gives their differences a place inside one coherent performance.
