Touch Screens: For the most accurate sound, play black and white keys together on touch screens. Treating Keys in Chords: When black and white keys appear in a chord, treat them as all white keys. For example, the chord [T0ep] can be played as [t0ep], with only a minor sound difference. Alternative technique for play the chord [T0ep]: - a. Press the black key 'T' (Shift + t) first. - b. Quickly release the Shift key. - c. Then press the remaining keys 0, e, and p simultaneously. - If done quickly, it will sound as if all the notes are being played at the same time.
