Have you ever been around musicians or sung in your school choir? If so, you have probably heard of the term 'Octave' even if you are not a musician. Apart from making your piano lessons easier, octaves serve the purpose of deciding the range of your piano. In modern times, piano keys range from 32 to 96 with a wide range of octaves. Believe it or not, learning how many octaves on a piano and the significance of it can actually make your learning process smooth and help you buy smart.
What is an Octave? If you are new to the piano, you might be wondering what an octave is? Well, the word octave derives from a Latin word, 'Octo,' which means eight. To put it simply, an octave is an interval between two notes or pitches of the same name. Here lies the secret of the piano keyboard. We'll get back to it later. You might be wondering why it is called an octave? Well, if you look closely at the piano, you will notice that any note repeats after eight notes. Hence, it is called an octave. For example, if you start with a C note, you can actually count eight notes from there to get to the later C note. The distance is always the same, even if it's higher or lower in pitch.
Quick Trivia: If you play the middle C note on the piano, the hammer will hit the middle C strings and make them vibrate at a frequency of 256 times per second. Similarly, if you press down the C note an octave higher, the strings will vibrate 512 times per second. The higher a note gets, the higher the frequencies of strings become.
How many Octaves are there on the Piano? There are various types of pianos with different numbers of keys. A full-sized piano comes with a total number of 88 piano keys, including 52 white keys and 36 black keys. There are 7 full octaves in a piano. Playing an octave means playing the white keys, AKA major notes. Although, each octave also includes 5 black keys, which are the minor notes in an octave.
History of Octave Has it ever occurred to you why there are 88 keys in a piano? Well, to seek the answer, we need to delve deep into the history of the piano. The closest predecessor of the piano is the harpsichord. Naturally, composers from the Renaissance and Baroque periods composed their music for Harpsichords. Constructed with 60 keys, harpsichords limited the composers to only 5 octaves. Also, they had to pluck the strings manually with a plectrum; the hammer was non-existent back then. According to music historians, around the end of the 17th century or the beginning of the 17th century, an Italian harpsichord maker and instrument technician named Bartolomeo Cristofori created a new hybrid instrument (both string and percussion) with a damper system and a hammer. Italian poet Scipione Maffei described the newly invented musical instrument as a quieter and louder version of the harpsichord. From this remark, the instrument got its original name Fortepiano (literally translates to loud-soft). Fortepiano was nothing less than a revolution in music history. It changed the course of piano forever and opened up a whole new musical range of the piano. Almost a century later, the musical range of a piano rose up to 7 octaves. Famous composers like Friedrich Chopin, Beethoven, and Franz Liszt composed their divine piano pieces in 7-octave pianos. Piano manufacturer Steinway introduced the modern-day 88-key piano in 1880, including 7 octaves and 3 extra keys. As we all know, modern-day pianos come with a total number of 88 keys (52 white keys and 36 black keys), divided in 7 full octaves. [ays_quiz id="2"]
Do I have to Memorize all the Piano Notes?
I was once a beginner, so I can understand how intimidating it can be to sit in front of a piano (come on, I'm talking about 88 keys) when you know nothing. The mere thought of remembering all the names of the notes is itself overwhelming. However, learning to identify the octaves can save you from misery. As the notes repeat themselves in every octave, it is wiser to memorize the notes within an octave. It means all you have to memorize is the names of 8 white keys and 5 black keys. It already seems easier now, right? If you can memorize all the notes and patterns in an octave, there is no need to memorize every single key from the whole key set.
