Amor por Trás da Melodia (2022)

Both are costume romance dramas about musicians where music is a huge part of the plot. Love Behind the Melody is a really great show that is underrated and flew under the radar, which looks like Echo of Her Voice might be similar in that regard as well.

Both are historical dramas centered around talented musicians. Both have a similar tone.
..............................................

I think they give similar vibes since they're both related to music but LBTM has a fantasy element.
