There are a lot of piano players who are also well known composers. And there is good enough reason for this. The piano allows you to play about ten notes at one time. On the guitar, you can only play six. There are even some piano players who can play more than ten notes at once. On the piano, each hand can play something really different. The instrument allows you to play different parts simultaneously. And this advantage helps give the players a good chance of coming up with really beautiful musical pieces on the instrument. And for the same reason, more musicians or composers focus on playing the piano.
But this does not mean that the guitar is not a very useful instrument when it comes to composing songs. On the contrary, the guitar is one of the most useful instruments when it comes to composing music. It allows you in on a very different compositional perspective. And this advantage will be able to help you come up with a piece that you will not have come up when you use the piano. And this will also greatly benefit a freelance composer, like you.
The piano works a lot differently than a guitar would. The chords are formed and played differently. The melody notes are played above the chord on the piano. It can be argued that playing the melody and the chords at the same time is a lot easier on the piano, it is still important to know that you can compose and play songs on the guitar as well. Remember that notes and chords can be easily moved around the guitar. And the variety of chords on the guitar will help you come up with really great progressions and melodies that will definitely be a big help in your composition. Also, there are a lot of things that would easily just fall into place on the guitar that will be almost impossible to do on a piano. Take for example, sliding around chord shapes. This simply means that people who make music with the guitar will find it really easier to be able to slide through the chords than those who are using the piano.
Of course, it can also be said that there are things that can be done on the piano that will be difficult if done on the guitar. There are things that you may write that are just impossible to do on a guitar. And this just means that it will be a great advantage if you know how to compose songs with more instruments. Each of the instruments that you use will contribute to giving the songs a different perspective and help spice it up a little bit. That means you will get more variation in to the songs that you write.
There is no debate in which instrument, piano or guitar is much better to use when it comes to composing music. The idea here is to start with the use of an instrument that can play chords and then supplement the melody with harmonic devices. As long as you have an instrument that plays chords, it will be great to use for composition. Explore what you can don on the guitar that you will not be able to do on other instruments both when you play and when you compose. There is one unique characteristic in every instrument. And that is something that you can use to come up with really great music.
