Untimely many songs do end on the bottom note, the trick is to delay this so that when you finally do it land on the bottom note it will have a stronger sense of closure. Delaying an ending on the root note sets up some nice tension in your musical ideas and gives your songs a sense of progression and resolution. Like taking a little musical journey and then returning safely home.

How to Apply This: Some Simple Exersises
As I teach in my classes, one of the best ways to Play from the Heart is to really understand the NAF pentatonic minor scale and the implied harmonies that can be found in the notes. Each note in the scale has it's own weight, or gravity, relative to the other notes in the scale. Those with less weight tend to move to those with more. Knowing and understanding these relationships will allow you to exploit this natural phenomenon and will help give your tunes an implied harmonic motion. Normally an instrument that can produce chords plays harmonies, but you can create the illusion of harmony by the notes you choose for your melodies, especially at the ends of phrases.
