The musical composition of any type of music is dependent upon the types of music pieces used to make the music itself. The word ‘piece’ usually refers to the instrumental compositions and it was initially a word that was used to describe this in the 17th century. The term is used when making sonatas and symphonies nowadays. Today different types of music pieces are compounded together to make music. Some pieces may be self-contained though. When the same sort of musical material is repeated over and over again it is said to be in strophic form which is one of the various types of music pieces. If you listen close enough to a piece you can tell whether or not a piece is playing repetitively.
Many artists do use these types of music pieces today. In some cases certain changes may be brought about though most of the piece would be repeating itself. This is referred to as a theme or a variation. These types of music pieces basically have the same type of music playing over and over again but certain variations in the way they are played would make them sound different at particular intervals. That is why they are referred to as variations too.
Another of the various types of music pieces is binary form. In binary forms what happens is that there are two very different themes that are played and they are alternating between fast and slow and you will notice that sometime artists, while singing, do use binary forms. You will be able to tell the difference between two different types of themes because they are very distinct and both of them repeat themselves. Ternary forms are those types of music where a theme is repeated twice after which a new them is introduced.
Then there’s the rondo form which is another of the many types of music pieces that you would come across. These types of music pieces consist of contrasting sections that are referred to as episodes. The themes that recur may do so symmetrically or asymmetrically and in some cases the theme may be varied at different intervals while in other cases they may develop towards the episode instead. Variational types of music pieces are those where the music type constantly varies- so where a theme is played twice and a new piece is introduced and this happens over and over again, there is a variational music piece. Again, if you listen to these you can tell that there are 2 distinct pieces after which another piece is introduced.
The term ‘music pieces’ is not technical at all and it simply refers to different types of music pieces that are contained within themselves. You will see that most musical pieces are actually contained within themselves and these are used in the music industry frequently today. Think of music pieces as blocks of music to be able to understand the concept of music pieces and you would be able to understand it better.
