In the very beginning of sound I hear piano and hi hat probably, but there is still a 3rd humming kind of sound which follows the chords I think what is it? I'm trying to make cover for the song and I need to know what kind of instrument it is, or atleast I need to know how to and where to look if I want to understand about various instrument sounds in music I hear. Because I cannot recognise instruments many times.
I'm new for this site, apologies if I have framed my question poorly. :)
I play guitar and classical piano but am very new to digital piano and yet can't recognise if this sound was actually made using synthetic piano.
