Hi,

Can anybody evaluate my post which has already been posted to Native instrument previously and tell me if I am on right or NOT?

I am a pianist who enters official exams and uses the fully weighted buttons of MK2 but the physical dimensions of the keyboard buttons (white Keys) are not matched with Yamaha and official pianos? Any help from Native instrument????

    Alas your question is far from as simple as you would like it to be. Apparently there can also be size different between e.g. grand pianos and upright pianos. E.g. someone reports that , quote : "My Yamaha with dynamic light keys has a 3-4 mm narrower octave than the ones with hammer action pianos."

    A :

    First take a look at the Size and historical variation section of the Musical keyboard on Wikipedia !

    I also found this quote on StackExchange :

    Quote : John Callahan of Callahan Piano in the San Francisco Bay Area, a Steinway restoration specialist.

    Please be nice to him, he gets it right every day from tuning to restoration and beyond.

    "You are correct, 100 year old piano keys will vary slightly in width. Some of that is the original tooling and cutting (piano keys are sliced like bread from one piece of material) and some of the variance can be from wear. The keys at the far ends of the keyboard will be a good bit wider on an older, heavily played instrument than the keys in the middle of the keyboard, where the most playing occurs."

    "No standard width. You can measure many different pianos, and while they will all be within a fairly standard range, you will see differences. Same goes for the sharps.

    This also holds true for many other piano dimensions. Keytop thickness, head length (distance from the player's end of the natural key to the cutout for the sharp), tail length, height of the keytop off the floor, height of the pedals off the floor, etc."

    Usually , despite many accusations then you will never find me pasting/using AI generated stuff but the below I have taken from poe.com which to me appear to be AI generated stuff :

    Yes, there are some differences in the standard length and width of piano keys between different types of pianos. The variations can be found in the dimensions of keys in different types of pianos such as grand pianos, upright pianos, and digital pianos. Here are some general differences:

    1. Grand Pianos: Grand pianos typically have longer keys compared to upright pianos. The standard length of keys in a grand piano can range from about 135 to 145 millimeters.

    2. Upright Pianos: Upright pianos generally have shorter keys compared to grand pianos. The standard length of keys in an upright piano can range from about 120 to 135 millimeters.

    3. Digital Pianos: Digital pianos aim to replicate the feel of acoustic pianos, and they often try to adhere to similar key dimensions. However, there can be some variations in the length and width of keys among different digital piano models.

    It's important to note that while there are general standards for key dimensions, manufacturers may have slight variations in their respective models. It's always a good idea to check the specifications provided by the manufacturer for the specific piano you are interested in.
