I also have a ‘real’ upright piano now and can enjoy the gorgeous tone-colours and extra touch-sensitivity of this instrument. For anyone playing piano at grade five level and above this is very important. However, it does need regular tuning! For me, having the piano tuned 2-3 times per year is an absolute necessity – I don’t think it is good for any student (or professional) to have to make do with an out-of-tune instrument. That would in fact do harm to your musical aural training and development. It is also vital to have enough space for the piano in your home: keep it in front of an inside wall so the temperature and humidity will be more constant and the pitch may be more consistent.
