Another way of naming the different pitches is by using syllable names:. Musical pitches can also be altered a half step higher or lower with the help of accidentals: sharps and flats b. All in all, there are 12 different "pitch classes" in the western music tradition.
On a piano, you can see them as 7 white and 5 black keys. Each pitch is a semitone apart, and this pattern is repeated higher and lower. The easiest way to see this is on a piano keyboard. Here you can see how the notes are repeated again and again:. In this musical star, you can see all the 12 chromatic pitches in Western music theory organized in a circle of semitones.
Inside the star are lines that connect the pitches to show the relationship they have with each other. It shows the relationship between the first note of a scale Tonic , the fourth Sub-dominant , and the fifth Dominant. How high or low a music pitch sounds depends on how fast or slow something vibrates. By changing the number of vibrations, or sound wave cycles per second, called Hertz Hz , the pitch will change.
To put it simpler, by stretching a string, for example, the sound when you pluck it gets higher smaller and faster vibrations. And when loosening the string, the sound gets lower larger, slower vibrations. Any instruments tuned this way are tuned in concert pitch.
Other instruments that do not have the same tuning, are transposed. For example; a piano plays the note C. This is a real C. A trumpeter plays a "C". But instead, it sounds like a Bb! To avoid confusion at rehearsals with transposed instruments, you have to define whether the written music should be played as written or if the concert pitch should be used.
Curious about note values and rests? Note values are how long a note or rest is. Learn how to count the beats in music notes and to understand rhythm in music. The key signature tells what scale a piece is made from. It's what you see as the combination of either sharps or flats in the beginning of a music staff. All Rights Reserved. Online Piano Coach. The Flute has a high music pitch. Pitches are named after the first seven letters of the alphabet: A B C D E F G This pattern is repeated for a higher pitch or backward for a lower and lower pitch.

Whether you pluck a piano key or strum a guitar string or blow into a saxophone, that instrument produces a sound wave. A sound wave is just vibrations of air molecules that go back and forth, creating a wave of pressure that travels from the instrument that produces the sound and is picked up by our ears.
The main property of a sound wave is its frequency , which is just a word for how fast the cycle of the wave is. This is all a bit technical and mathematical, but just know that pitch is basically the frequency of a note.
The higher the frequency, the higher the pitch and vice versa, the lower the frequency, the lower the pitch. For example, a tone can have a pitch of Hz, which means the sound wave produced by the note repeats times in one second. The human ear can only hear tones with pitches between 20 Hz and 20, Hz, and almost all of the music you see and play would be between 50 Hz and 8, Hz.
Same when you clap your hands or clink a fork to a glass of water, you are producing a tone with a pitch, but it is not necessarily a note. A note refers to specific pitches, and in Western Music a note refers to one of 12 named tones that all music is made from — the notes of the chromatic scale. Now, each of these notes can be repeated in different octaves, and so there is not one specific pitch that is associated with each note.
For example, on a regular piano, the note C can have one of 8 pitches: Notes that are in the same scale, and specifically notes from the same chord, are mathematically related by pitch. This A has a frequency of Hz. But to get the frequency of the A an octave higher you double the pitch and the frequency. This continues up and down the entire frequency range — every A found in music is either 55 Hz, Hz, Hz, Hz, Hz, Hz, and so on.
