A grand piano is characterized by its horizontal shape and larger size compared to upright pianos. The strings and soundboard are positioned horizontally, which allows for a longer string length and larger soundboard area, producing richer and more powerful tones. Grand pianos typically come in various sizes, such as concert grands, baby grands, and medium grands, each offering distinct sound qualities. The design also includes a more complex action mechanism, allowing for greater control over dynamics and expression while playing.

In the movie "Grand Piano," the highest quality piano featured is a Steinway & Sons grand piano. Renowned for their craftsmanship and sound quality, Steinway pianos are often considered the gold standard among concert pianists. The film uses this iconic instrument not only for its musical excellence but also as a crucial element in the tension of the plot, highlighting the protagonist's talent and the high stakes he faces during his performance.

In the movie "Grand Piano," the phrase "grand pianos are free" is a metaphorical expression highlighting the protagonist's struggle and the high stakes he faces. The main character, a concert pianist named Tom Selznick, is forced to perform while a sniper threatens his life, implying that the beauty and art of music come at a dire cost. The concept reflects the idea that true artistry often involves sacrifice and danger, rather than implying that these instruments are literally free.

In the movie "Grand Piano," the primary cons of a grand piano relate to its size, cost, and maintenance. Grand pianos are typically large and require ample space, making them less suitable for smaller homes. They are also expensive to purchase and maintain, with tuning and repairs needing professional attention. Additionally, their weight can make them difficult to move. In the context of the film, the tension and pressure faced by the protagonist while performing are heightened by the grand piano's significance and the stakes involved in his performance.
