@musique_et_emotions: 🌟 Both acoustic instruments made up of mechanical parts that do similar things. 1. The pianist presses a key 2. The key activates a hammer 3. The hammer strikes a string 4. The string vibrates, creating sound 5. The sound is amplified by the piano’s wooden soundboard 🌟 Upright and grand pianos are similar in the sense that they are both acoustic instruments made up of mechanical parts that do similar things. In a nutshell, this is how an acoustic piano—grand OR upright—works. 🌟 Grand pianos typically have a larger soundboard than an upright. This means grand pianos sound louder and richer. 🌟 Grand pianos typically have a sostenuto pedal as their middle pedal. Meanwhile, the middle pedal of an upright piano is usually a practice pedal. 🌟 Both uprights and grands have an una corda pedal as their left-most pedal. In a grand, pressing the una corda shifts the hammers to the right so that they hit one string instead of the usual two or three. In an upright piano, the una corda moves the hammers closer to the strings. In both cases, playing with the una corda pedal creates a softer, more rounded tone. . . . . . . #grandpiano #uprightpiano #piano #music #emotions #musicandemotions
