Lefty Mode

One of the major features of the Verti-Chord Keyboard app is to enable a user to play all chords of a particular chord type using just the finger position for a C-chord of that chord type, thereby reducing the complexity of piano keyboard playing by an order of magnitude.

The Lefty mode further reduces this complexity by a factor of two … here is how.

By selecting the Lefty mode (as shown above), a left-right mirror image of the keyboard is created, such that the left hand can now play any chord with the same finger placement as that of the right hand, thereby eliminating the need for a user to learn multiple finger placements per chord.

Slide Mode (Smoke On The Water)

I am not saying that the Verti-Chord Keyboard Slide mode was designed exclusively for Smoke On The Water (released 1972 by Deep Purple on their Machine Head album), but it certainly was a big factor.

Ever try playing that infamous guitar riff on a piano? It does not work very well because sliding from one note to another on a piano involves two distinct note attacks, rather than just the one attack and frequency transition of note sliding on a guitar.

Electronic piano keyboards often employ a pitch wheel to better simulate the guitar note bending/sliding techniques, but this method has two distinct disadvantages: 1) it requires the use of a second hand; and 2) it affects all notes being played equally; both of which can be limiting factors in achieving a desired sound.

The Verti-Chord Keyboard Slide mode enables the user to bend and/or slide notes using only the one playing hand, and to do so on an individual basis when multiple notes are being played … here is how.

Restart the Verti-Chord Keyboard app and select the placard option for proceeding to Verti-Chord. Exit the Song mode and select the Slide mode, as shown in the above figure.

Play, in succession, B 4th, D 4th, and E 4th (i.e., place the thumb on the note section of the first key from the left corresponding to the named 4th, and place the forefinger on the fourth key from the left, as shown for E 4th in the above figure). Hold the B and D 4ths for about one half second each, and the E 4th for a full second. Sound pretty good so far?

Now repeat those same 4ths as previously played, except this time, before holding the E 4th for one second, quickly slide your thumb (and forefinger by an equal amount in unison) up to the F note section, and then just as quickly back down to the E note section. Did you hear that?

Now repeat those same 4ths as previously played the first time. Add another half-second D 4th and a one-second B 4th, but before holding the B 4th for one second, quickly slide your thumb (and forefinger by an equal amount in unison) up to the C note section, and then just as quickly back down to the B note section. Did that sound just like the guitar riff?

If you really want to get fancy, on each one-second hold, slide your two fingers quickly up and down repeatedly in short strokes to create a tremolo effect on the hold. That is it. Just be sure to repeat the entire riff several times through for good measure.
