    The action of a piano is the mechanism that connects the keys to the hammers, which strike the strings when a key is pressed. The two main types of piano action are upright and grand.

    1. Upright Piano Action: In an upright piano, the strings and action are positioned vertically. When a key is pressed, the hammer is propelled straight towards the string. After the string is struck, the hammer falls back due to gravity. This is called ” direct blow”. The advantage of this system is its simplicity and compactness, which makes it ideal for vertical pianos where space is limited. However, the disadvantage is that the hammer cannot rebound quickly from the string, which can result in a less responsive and somewhat heavier touch.

    2. Grand Piano Action: In a grand piano, the strings and action are positioned horizontally. When a key is pressed, the hammer is propelled towards the string at an angle
