I have downloaded (free) pitch coach and that helped.. but hten i got bored.. What I really want to be able to do is to play any tune in any key by ear which isn’t really the same.. however I think perfect pitch is possible and lik anything has to be worked at – I reckon if you make yourself aware of pitch at regular intervals – say do five minutes every three hours, or indeed do it as you can set the programme to do.. every 5 or ten minutes test yourself and do this for at least a month and probably a bit longer then it should develop.
