Acople

Acople
 

No sé cómo traducir ''acople'' en este contexto. Agradezco su ayuda.
Saludos.

La velada -con un acople particular del piano y la guitarra- puede catalogarse como familiar, pues se reúnen el padre y la hermana del protagonista: los guitarristas Eduardo Martín y Galy Martín.

The evening, with a special ¨acople¨of piano and guitar, can be described as a family reunion, since the pianist's father and sister will perform together: guitarists Eduardo Martín and Galy Martín.

accompanyment

Thanks so much for your help. I think it fits pretty well in my context.

I prefer 'marriage' or 'coupling'.
An accompaniment is what the piano is playing, but only if he is not also featured. An accompaniment is not the melody.

Joining a pianist with guitarists cannot be termed an accompaniment.

Piano paired with guitar is more equal than piano accompnied by guitar.

We don't know how the piano is paired with the guitars. The pianist could play an accompaniment, the melody or a counter melody (or a combination of all three). We don't know what the guitarists are playing, but since they are a duet, we can count on a melody and a counter melody or accompaniment.

All I said was that substituting 'accompaniment' for acople doesn't fit. This is because the three performers considered together are the acople.
That makes them an ensemble (un conjunto) or a trio in my way of thinking - the correct word describing the performers as a group.

Because they are all related to each other, 'marriage' came to mind as a good way to 'group' them together. There may be other words to describe the special gathering of the related performers for the evening performance.
