![]() White keys were traditionally plated ivory – which comes from tusks (such as elephant tusks). What are Black Keys Made of?īlack keys were traditionally made of ebony – a dense dark wood that glosses nicely. So what are the black keys on a piano for? They efficiently organize the 12 keys per octave in a recognizable pattern. 3 followed by 2, allowing for visual distinction and 12 notes to a scale all in one! In fact, the placement of the black keys is how intermediate and advanced pianists internalize note names. Notice there is no way to distinguish one note from the next at a glanceīlack keys every other note is hardly better.Īnd finally our current layout. Let’s explore the function of the black keys by consider what a keyboard looks like without them. This eliminates the need for any extra keys, or complicated tuning systems. Modern pianos/keyboard instruments are tuned using the equal temperament system in which each note is 12√2 times higher than the note before it. Notice how the D♯ and E♭ are two slightly different pitches. One way around this was by providing extra black keys as shown in the YouTube video below. For example, historically tuning a keyboard to a C major scale often caused other keys to sound out of tune. Tuning so that each note is equally viable is tricky. Not only is 12 notes to an octave arbitrary. ( Research Indian Ragas for more information). For example the Druhpad, an old North Indian form of music, split the octave into as many as 84 units. Some cultures however, split the octave differently. Similarly plucking two strings, one that is half the length of the other will produce two pitches an octave apart.Īs music developed in Europe an octave was split into the twelve semitones westerners are familiar with. This is how all keyboards are organized right?ĭoubling a frequency produces a pitch exactly an octave higher. This is the layout of one octave on a standard keyboard. Do All Keyboards Have 5 Black Keys Per Octave? Since the 1970’s we’ve decided that we actually like our elephants currently ivory is not used in the production of piano keys. With white long keys the shadow creates a border. Using black long keys makes it difficult to see the shadow between keys.Ivory beats wood in durability ( which this elephant already knew) making them better suited to the more often used white keys. Historically white keys were topped with ivory, a tough bone tissue that can be found in the tusks and teeth of elephants, warthogs, hippopotamuses and even narwhals. Black keys were made from dark dense woods such as ebony.There are several advantages to our current white long key, black short key model. Some pianos, especially this old one from Mozart’s time (1750-1800), used black long keys and white short keys.Īttribution-Share Alike 3.0 Unported by Bapak Alex. (Based on these diagrams).Ĩ8 (standard grand/upright piano or keyboard) ![]() ![]() Depending on which note is the starting note the number of black keys on a piano can vary, but here is a rough guide. On a 61 key instrument (usually a keyboard) there are 25. There are 36 black keys on a standard 88 key piano (upright or grand pianos). Thus F is the enharmonic equivalent of E♯. For example, E♯ modifies E to the key usually referred to as F. Sometimes a sharp or flat will modify a note from one white key to another white key. This can be seen in the visual below.īlack notes aren’t the only ones that can have a ♭ or ♯ in their name. So, what are the black keys on a piano called? The black key are named D♭, E♭, G♭, A♭, B♭ or alternatively C♯, D♯, F♯, G♯, A♯. C♯ and D♭ are enharmonic equivalents since they are two names that refer to the same note. Note that the black key between C and D is called either C♯ or D♭. So the black key to the left of D becomes D♭. The flat (♭) modifier moves the pitch down, or to the left. So the black key to the right of C becomes C♯ (read C sharp). The sharp (♯) modifier moves the pitch up or to the right, by one key. The black keys are modifications of these notes. The white keys of the piano are A B C D E F G, and then the pattern repeats these notes are known as the “natural” notes. Unlike a piano’s white keys, the black keys have more complicated names.
