Looking for this instrument
[Help Finding Sample] Hi, I'm looking for the instrument that plays in the background of the linked sample; next to the piano. It is the main melody that is sandwhiched between the piano and the repeating bass (I isolated the song so you can hear it better). It sounds kind of bright and melancholic? Maybe it's an Accordion? To really spot it, it starts the song with the really long note and ends off the sound with the final 3 notes. Please help me find this instrument it would help a lot.
