The lead singer has to strain his or her voice to hit the high notes, so the group decides to change the key of the entire. First, let’s say you are playing in a band, rehearsing a Led Zeppelin song. This can come into play in a variety of scenarios. This happens because the horn traditionally did not have valves so the composers wrote the parts in different keys to accommodate the music. In music theory, key is the major or minor scale used to produce a piece of music, a music is called in a MAJOR KEY when it’s based on a major scale, a music is called in a MINOR KEY when it’s based on a minor scale. When we are talking about a song, modulation means to change key. As such, if a song revolves around a major scale, this means it’s in a major key, and if a song is built around a minor scale, it’s in a minor key. Even though the horn is an F instrument, you will find parts that are written in D or C or E-flat or other keys, and they are forced to transpose. In other words, a song’s key is the primary group of notes or pitches that come together to create the harmonic basis of a music piece. For example, I am also a French hornist and often there are pieces written in different keys from one another. However, there are some instrumentalists that do have to transpose. They only have to play the notes as written and everything will sound correct. He or she must know what key the instruments are in and be able to transpose the notes instantly to ensure they are correct.įor instrumentalists, it’s much easier. This is where it can become confusing because a conductor will have to transpose many parts of the score because an orchestral score is not written in concert pitch.
Many instruments are transposing instruments which do not play in concert pitch. This means that a saxophone pitched in E- flat playing a C will sound an E-flat on the piano which is in concert pitch. The saxophone is also a transposing instrument. This enables a saxophone player to move from instrument to instrument seamlessly. When you look at the family of saxophones you may realize that all the different types of saxophones are pitched differently – yet they all have roughly the same fingerings. You have the clarinet in B-flat, saxophone in E-flat, and French horn in F: why are they pitched in different keys? It seems it would be better to just write everything in concert pitch, wouldn’t it? Believe it or not, it makes a lot more sense to have some instruments in different keys. Without the sharps, it is a different pattern and, therefore, not a Major scale.When you think about all instruments being in different keys it can be confusing. This image shows that the key of D Major follows this same pattern. Notice that the pattern changes, which means that this is no longer a Major scale. Here's what it would look like without the B flatted.
The B is flatted so that the scale follows the same W W H W W W H pattern. The key of F, for example, has 1 flat (B flat). The key of C has no sharps or flats because it naturally follows this pattern. In the last lesson, we discussed that the W W H W W W H step pattern is the same for all major keys. Whole & Half Step Pattern in a Major Scale In Western musical notation, a key signature is a set of sharp ( ), flat ( ), or rarely, natural ( ) symbols placed on the staff at the beginning of a section of music. Let's discuss what all of these key signatures have in common. This little trick will help you quickly determine the name of the key signature when there are multiple sharps or flats in the key signature, but you may have noticed that this trick doesn't work for the key of F or the key of C. In this case, there is already a C# in the key signature, so this key is the key of C#. The quicker way to determine this is to look at the sharps already in the key signature. This means that half step above B# is C#.
Remember that there is a naturally occurring half step between B and C, which means B# is the same pitch as C. Why? The last sharp in this key signature is B#. It is not the key of E# because there is no E# in this key signature. This is the key of E because E is half step above D#, which is the last sharp in the key signature. This is the key of G because F# is the last sharp in the key signature. Sharpsįor key signatures with sharps, the key signature is the note name half step above the last sharp. It is not the key of D because there is a D flat in the key. This is the key of D flat because D flat is the second to last flat in the key signature. This is the key of E flat because E flat is the second to last flat in the key signature. Here is a list of all of the different key signatures:įor key signatures with flats, the key signature is the second to last flat.
