4/17/2023 0 Comments Music keys on pianoPiano keys are laid out in what are called semitones, or half steps, and are arranged to follow a chromatic scale (each key is one half step away from the adjacent one). (This is an over-simplification, but this is an article for pure beginners.) The first key (on the leftmost side of the keyboard) is an A and the final key (on the rightmost side) is a C. The keyboard has white keys that are tuned to play “natural” notes, and black keys that are tuned to play flat and sharp notes. When depressing the keys, you trigger hammers inside the piano to hit strings, which is what produces the sound. Thus the circle of fifths clearly depicts the two most important relationships in tonal harmony: tonic–dominant and minor–relative major.A piano has 88 keys, 36 are black and 52 are white. Each minor key is also entered on the circle, in the same position as its relative major. At F-sharp major, the key with six sharps, the circle shifts enharmonically to G-flat major, the key with six flats (they sound and look the same on a keyboard instrument). Each advance adds a sharp to the key-or, equivalently, subtracts a flat. Beginning at C, the top position, and proceeding clockwise, the keynotes ascend by perfect fifths (as in the tonic–dominant relationship). The circle of fifths is an efficient way to visualize keys, key signatures, and relationships between keys. The relationships between keys are at the heart of the tonal system, and the listener’s ability to perceive different keys and the process of changing between them (called modulation) adds immeasurably to their significance in musical structure. In contrast, the distantly related keys of C major and C-sharp major have no note names in common. They include the concepts of key, of functional harmony, and of modulation.ĭifferent keys are closely or distantly related according to the number of notes their diatonic scales share C major and G major, for instance, have six of their seven notes in common (differing only in F♮ and F♯) and thus are closely related. 2 in D Major (1802), for example, has three of its four movements beginning and ending with explicit harmony in D major (the second movement is in A major, for contrast). A composition, particularly an instrumental work, may be identified with a key designation Beethoven’s Symphony No. A short piece of music, such as a song or dance, may demonstrate only a single key and is said to be in that key longer pieces usually change key, even many times, but are organized and unified within a principal key that predominates at important points. The concept of key is fundamental to the system of tonality (the organization of notes, chords, and keys around a centrally important tone), the basis of most Western art music from about 1700 to the 20th century and beyond. In musical notation, the key is indicated by the key signature, a group of sharp or flat signs at the beginning of each staff. Accordingly, 12 major keys and 12 minor keys are possible, and all are used in music. Any of the 12 tones of the chromatic scale can serve as the tonic of a key. The central chord is the tonic triad, which is built on the tonic note. Key, in music, a system of functionally related chords deriving from the major and minor scales, with a central note, called the tonic (or keynote).
