My son is good with sight reading but not good in ear training, solfege. His Piano teacher train him once in a while ( just before their internal exams) for aural. I have been thinking of trying something on our own and thinking if I give some songs to him (just voice) and ask him to listen and try to play on piano. I have few songs in my mind i.e Let it go, Beatles Imagine and Pan's Labyrinth lullaby to start with ? Looking for suggestion on same, any idea is highly appreciable.
