Here's a quick tip for today. A few years ago I studied Debussy's "Images."
He quite commonly used an effect with chords that brought a very zen, fantasy-like movement and harmony. He would go up a IV multiple times, changing keys, or a minor third down, also changing keys.
For example: Start at F, jump to Bb, jump another IV and change keys to Eb, then jump down a iii and change keys to C.
Practice playing some melodies while using this technique. You might be surprised by the sound you achieve!
