It depends. Without knowing how weighted the keys are, the quality of the sound, the brand, age, maintenance history of the instrument, it can be difficult to tell without trying it out. If it’s a used acoustic instrument, similar to buying a used car, it’s also important to hire a licensed piano technician to examine the inside of the potential instrument before you decide to buy it. If it’s new: It can be hit or miss. You will need to do some careful research. Generally speaking, it’s rare that big box stores have the serious piano student in mind when selling instruments to the mass market.
