Selecting and Playing Styles - The Style Mode Using Auto Accompaniment - Multi Fingering The auto accompaniment function automatically generates bass and chord accompaniment for you to play along with, by using Multi Fingering operation. You can change the chords of the accompaniment by playing keys in the ACMP section of the keyboard using either the "Single Finger" or "Fingered" method. With Single Finger you can simply play a one-, two- or three-finger chord indication (see Single Finger Chords below). The Fingered technique is that of conventionally playing all the notes of the chord. Whichever method you use, the PortaTone "understands" what chord you indicate and then automatically generates the accompaniment. Single Finger Chords C Chords that can be produced in Single Finger operation are major, minor, seventh and minor seventh. The illustration below shows how to Cm produce the four chord types. (The key of C is used here as an example; other keys follow the same rules. For example, Bb7 is played as Bb C7 and A.) Cm7 To play a major chord: Press the root note of the chord. To play a minor chord: Press the root note together with any black key to the left of it. To play a seventh chord: Press the root note together with any white key to the left of it. To play a minor seventh chord: Press the root note together with any white and black keys to the left of it (three keys altogether). Fingered Chords Using the key of C as an example, the chart below shows the types of chords that can be recognized in the Fingered mode. s Fingered Chords in the Key of C NOTE: If the chord is inverted (i.e., C-E-G is played as G-C-E), the PortaTone will still recognize it as a C chord. The chord recognition system also has the following rules and exceptions: • Minor 6th chords are recognized only in root position, however; all other inversions are interpreted as minor 7th/ flatted 5th. • If augmented and diminished 7th chords are inverted, the lowest note will be recognized as the root. • 7th flatted 5th chords may be played with the lowest note as the root or the flatted 7th. • Augmented 7th and diminished 7th chords are interpreted as simple augmented and diminished. NOTE: The following chords are not recognized : B minor 6, Bb minor 6, and B augmented.
