I like the blue bars and the symmetry of the logo. Not too keen on using the treble clef though. Would also be nice to see the blue bars more resemble a waveform if possible, but nothing too crazy because I would want to retain the clean look currently.
Would love to see this latest version without the music note and just the blue bars and the white wave. If it is too simple, maybe elaborate on the white wave to offset the loss of the music note
I think it looks much better without the music note. Could I also see a version without the flat white line? Maybe some other variations you might have in mind? Also some different font variations would be great to see.
