Song means a musical composition with lyrics that someone could sing, and is often accompanied by an instrument or group of instruments. Some songs tell a story while others simply convey an emotion. Songs can be found in the form of folk music, as well as in classical and popular music from all around the world.
The songwriting process is often the longest and most challenging part of making a great piece of music. It can take weeks to perfect the chord progression, and then even longer to write the lyrics. Once the song is written, it needs to be practiced to perfection by the band or artist and then recorded, which can also take a very long time.
A good song should contain a catchy melody, which is known as the hook. The hook should be memorable and stand out both melodically and lyrically from the rest of the song. It should be the one part that people will have on repeat after hearing the song once or twice. The chorus is a good place to include the catchy hook since it embodies all the big ideas of the song in one memorable melody. The chorus is also the best place to put the title of the song, since it serves as the climax of the entire work.
Some songs do not have a bridge, but instead rely on the repetition of the verses to move the story forward. This is common in some pop music. Other styles of music such as folk music and sea shanties often use repetitive rhythms to help coordinate activities, or to tell a story.
