ËSPECIAL NOTE - ProChord™
When you scroll through the Extra Voices in each Voice Category, you may have noticed the legend, “Pcd”
You will see “Pcd” in several of the Voice Names in the A.PIANO, WIND and OTHER Voice Categories.
“PCD” is an abbreviation for ProChord.™ The next paragraphs will explain in detail how to use the ProChord™
feature.
What Is “ProChord™” - PLEASE READ
ProChord™is a unique feature of certain Hammond Organ models, including the Sk-series, which allows you to play
professional right-hand harmony while playing a single-note melody. The harmonization applied to the melody is
determined by which chord is played by the left hand.
On the Sk1, the SPLIT feature must be enabled (SPLIT Touch Tab “ON”) and a note or chord played to the left of the
Split point in order for the harmony to sound when notes are played to the right of the Split point.
On the Sk2, a note or chord must be played on the Lower Manual in order for the ProChord harmonyto sound when notes
are played on the Upper Manual.

EXTRA VOICE Section
18
ProChord works like this: When notes or chords are played on a Lower Manual and a note is played on an Upper Manual,
the note represented by the key played on the Upper Manual is heard along with a scored harmony pattern which sounds
according to the Chord Root and Chord Type selected by the notes played on the Lower Manual. The Chord Root is the
letter name of the chord (F, A, B=, etc) while the Chord Type is the denomination of the chord (Major, Minor,
Augmented, etc.). The ProChord feature on the Sk-series instruments will recognize 26 different Chord Types in
response to notes played on a Lower Manual. The following page will show how to play the five basic Chord Types
using a minimum number of notes.
ProChord Chords
Major Chords
To play a Major chord, play the key that is the name of the chord you are playing. For example, to play a C Major chord,
Play a "C" key on the Lower Manual.
Minor Chords
Minor Chords are formed by touching and holding two keys. To play a “C” Minor Chord, first touch and hold the key
that is the NAME of the chord. Second, determine the note which is a minor third above the key you are holding by
counting three (3) keys to the right not including the key you are holding. For a C Minor Chord, this note is "E ":
=
1. C
2. E=
Seventh Chords
Forming a Seventh Chord requires touching and holding two keys. To play a "C" Seventh Chord, play the key that is
the NAME of the chord. To determine the second key, count two (2) keys to the left of the first key (B if you are playing
=
a C Seventh Chord). Do not include the first key in your count.
1. C
2. B=
Diminished Chords
Forming a Diminished Chord requires touching and holding two keys. To play a "C" Diminished Chord, play the key
that is the NAME of the chord. To determine the second key, count six (6) keys either to the left or the right of the first
key (G if you are playing a C Diminished Chord). Do not include the first key in your count.
=
1. C
2. G=
Augmented Chords
Forming an Augmented Chord requires touching and holding three keys. To play a "C" Augmented Chord, play the key
that is the NAME of the chord. Next, count three (3) keys to the right. Finally, count three (3) more notes to the right
of the key you just added. For a C Augmented Chord, these three notes are:
1. C
2. E
3. G<
NOTE: In addition to the above method, the entire chord can also be played to produce the same result.
