Understanding Music Theory – What is a Key?
Learning to play or compose music is far more interesting when you understand music theory. In music theory, the concept of a key is important in both composition and performance. If a musician is knowledgeable in the art of music theory, they can presumably identify the musical key that best describes a particular piece of written or performed music.
In general, a key is defined as “a group of pitches organized together by a particular arrangement of half steps and whole steps.” The notes that are contained in a key of music are usually named for the first and last notes of the key. As a result, a composition written in the key of D would be composed of notes described by D and any notes in the order of half steps and whole steps contained between the limits of D.
In actuality, there are twelve major keys and twelve minor keys. Each key is said to have its own corresponding scale, and each of which has a specific sound or flavor that is exclusive to that key. For example, a song written in the key of A-flat major tends to be more cheerful than a song written in the key of F-sharp minor. This is due mainly to the fact that one key is major and one is minor.
What is Transposing
Transposing is the process of changing the key of a given song. Transposing is necessary because some songs may not sound good when played in its original key. For example, some singers may not have the range of a vocalist in another genre. As a result, transposition is the most viable option to make the song sound well with the vocal range of any given singer.
Additionally, transposing a piece of music can help to evoke different feelings from the same music. For instance, a song that is written in a minor key may feel brooding and melancholy, while transposing it up a few keys could make it more cheerful. This illustrates how powerful transposing can be in manipulating an audience’s emotional connection to the song.
Led Zepplin and Music Theory
The great British rock band Led Zepplin is widely regarded as one of the most influential music acts of all time. Despite their laser focus on theatrics, Led Zepplin was far from incompetent when it came to the role that music theory played in their compositions. Although most of Led Zepplin’s pieces are based in traditional blues scales, there is ample evidence that the band understood and embraced the importance of music theory in their music.
In many of Led Zepplin’s most popular songs, there are often intentional modulations, or changes in key, built into the song’s structure. Moreover, Led Zepplin often flipped traditional harmonic conventions on its head by switching from major to minor keys mid song to elicit a more intense effect on the listener. These two techniques point to the band’s use of music theory to produce different sonic textures and produce unpredictable yet beautiful music.
Varied Keys of Led Zeppelin Songs
Music is far more interesting when it is composed in various keys. Numerous Led Zepplin songs are written in a variety of keys and even more so, many are modulated keys, which change during the course of the song.
Though the majority of Led Zepplin’s songs are written in traditional blues scales, the group often experiments with keys in its music to create an exciting and dynamic sound. Led Zepplin songs like “Stairway to Heaven,” “Kashmir,” and “Immigrant Song” all employ multiple keys throughout the course of the song in order to create different sonic textures.
Additionally, it is important to note that the band often switched from major to minor keys in order to emphasize the contrast between dark and light sonic qualities in their music. In the case of “Kashmir,” the band begins the song in the minor key of E-flat minor, before taking an unexpected modulation to F major midway through the piece.
