The songtexte, or lyrics, are the words that set a songtexte to music and can be found in various forms. For example, the latest versions of Apple devices offer a feature called 'Synchronized Songtexts' that allows artists to sync their lyrics with the song's melody.
Lyrics are the key to a song's success. They should tell a story, provide essential information to the listener, and enliven the musical experience. They can also be creative and use literary devices like metaphors, similes, and personification.
A hook is the first sentence of a song's lyrics that grabs the listener's attention and sets up a storyline. The other lines in a song should support the hook. It's a good idea to write the song's topic and hook first, then develop the rest of the lyrics from there.
