Really, it depends on the lessons! For our introductory Conservatory Sampler class, no piano is needed, as we spend ample time in the lesson playing on actual full-sized acoustic pianos. For private lessons, a full-sized acoustic or digital piano (88 weighted, touch-sensitive keys and a pedal) is required. Small table-top keyboards and other “toys” will be a waste of your time and money within a few short months.
