It is essential to have a reliable instrument that suits your requirements for both lessons and daily practise.
An instrument to practise on between lessons is essential before starting the piano.
A more affordable option when making that first step is to buy or trial a digital piano.
A digital piano with weighted keys would last a student until a grade five standard or around five years of playing. At this point you would consider buying a real piano.
A good starting point would be the Privia PX 150 digital piano which Morris Brothers Music have for rent/hire at around $55/ month. You could also buy one outright for $699 complete with pedal and stand and USB input. A record and playback function is useful for the student’s own listening and monitoring.
Morris Brothers Music located in Stafford, has a wide range of new and second hand pianos as well as higher entry digital pianos if you were after something more professional.
