Making Your Own Music
Playing your favorite music is fun, but you can develop a stale "copy and paste" sound by playing other people's music all the time.
Here's how I have learned to avoid this and make my own music. First, I select a scale (for example an easy Pentatonics Major such as C, F or G). Then I create my owm music based on this simple scale. You can select any order that sounds good using these five notes, then repeat them to make a "loop". In this way, you begin to create your own "feel" for music. Before you know it, you will notice patterns, octaves, fifths and other sounds that you don't ever think of when your are just repeating other people's music.
Once you create a pattern or song you like, why not record it using your computer? You could install software to edit and play back your recording. Consider Guitar Pro (for a modest cost) or TuxGuitar (free for Windows, Linux and Mac).
