So to start off, you need a good song that conveys something and touches people’s hearts and minds. This has to be rendered in such a way that the message hits home. This is where music beats and melodies come in. With the amazing number of instruments and a multitude of software, you can try and mix the song up to see what comes out.
If you are the slightly genius kind, you can even frame a tune in your mind and then use the right instruments and electronic mixers and synthesizers to compose music. When good lyrics combine with soul stirring rendition, and if you can manage to dish it out with some accompanying instruments, you are done. When all these ingredients come together to create something magical that appeals to the masses, that is when you have managed to create undeniably good music.
Remember that where music is concerned beauty is in the ear of the beholder and there is no set rules to say what will appeal to a person.
