Everyone is trying to figure out the recipe for composing music that will appeal to the listeners of the world. Today so many believe that you have to be flashy and jiggle your money maker on YouTube to make it to the top. That may work, but it could just as easily backfire and permanently halt your music career. So let's take a more productive route to the top of the charts by composing music that is emotional and has a unique sound. Original music is always embraced by more listeners than the copycat sounds of past musicians.
For starters, keep the lyrics slow and broad. The more you can dial in a larger audience, the more your popularity will grow. By this, I'm suggesting that you sing about things that affect all humans on one level or another. Songs about human emotions are usually the one that most listeners can associate with on a more personal level. If you can express an emotion through your music that resonates with an emotion that the listener regularly feels, this will establish a connection on a deeper level. Lyrics alone are usually not enough to make this connection, the music has to carry just as much emotion to make the bond solidify.
Now you don't need to compose a symphonic masterpiece to capture emotion in your music. In fact, I'd suggest you keep the music more sparse and focus on making the sounds very dynamic and rhythmic. Space between notes and sounds can be deeply emotional. When the groove has moments to breathe, it creates a more dramatic sense to the music. Now not every song you write has to be slow and sparse, but finding a common thread to weave through all your songs will help listeners find appreciation in your music as a whole instead of just the one hit song.
I'm always happy to listen to your music and give you my feedback. My opinion is just that, my opinion. I'm not the one to make the ultimate decision on what is a hit record, I'm just one person in a huge sea of music lovers. Keep in mind that not everyone is going to love your music. Make music that sings to your own soul. That's the first step on the road to making a hit record.
