A liitle instrumental

Just made up by Philippo, George while Fransesca was taking video and giving good vibrations. The melody repeats La, Si, Do, LA, Si Si, Do, La La, Si, Do,...etc. The bass is La, then Fa, then Re, then Mi. So suitable bass code ie harmony or chords is La minore, F majore with majore 7th, Re minore with majore 9th, Mi minore with minore 7th.
