The Piano Bundle course enables you to play the melody and full chords easily, whilst still being able to use the auto accompaniment facility on a keyboard (to add bass and drums etc...). You can do this using the DecPlay PianoTabz numbers method (which is by far our students preferred choice for beginners and also for advanced playing techniques) or using standard guitar type chords.
If you are using a Yamaha Tyros keyboard, the setting for this is 'Multi fingered mode' - more details at :-

Of course you can also use the single fingered mode if you prefer, but the course offer you the ability to break free from the limitations of this and to develop your playing style from beginners through to intermediate and advanced styles and to build the foundation to be able to learn how to play both melody and chords by ear. This is also useful is you wish to play on a piano or keyboard other than your own.
