How to Play

In a few simple steps, you can be playing the Auto Bass right along with your favorite song or with a group. The quality and pitch of the sound are produced digitally, which means, your skill level doesn’t affect the sound. You can’t lose.

If you are familiar reading or playing music, picking up the Auto Bass will come easily to you. The manner in which the notes are selected is very similar to the way chords are selected on an Autoharp and as simple.

Never played an instrument before, new to reading music? Don’t worry. We take the guesswork out and get you making music right away.

Step 1:


Connect the Auto bass to your external amplifier/speaker from the audio output which is available from a 1/4″ phono jack at the rear of the base.

Step 2:

Turn the Auto Bass on and select the desired volume with the (on/off – volume) control,  the smaller  knob on the top of the instrument base. The LED indicator will light up for a few seconds then go out indicating that the instrument is ready to play.

Step 3:

Select the desired musical key (found at the top of your song sheet or as indicated by the music score sheet) using the larger knob on the top of the instrument base.

Step 4:

Place your hands on the Auto Bass fingerboard. The left hand near the top of the neck with the fingers positioned over the upper set of four touch switches.

Place the right hand lower with the fingers positioned over the lower set of four touch switches.

Step 5:

With the fingers of the left hand select the desired chord by pressing the “string” against the appropriate touch switch(s) (I,II,IV,V, VI) [See the diagram.]

Step 6:

Now while keeping the chord switch selected by the left hand closed, select the desired note with the fingers of the right hand, either the  “root” note or the “5th” note of the selected chord (the bottom two switches of the lower set, see the diagram.)

Note Selection

Chord Change

In general, when music calls for a chord change, or at the beginning of the first chord, the note played on the first beat of the measure is the “root” note, followed by the “5th” on the second beat, and so on.

Bass Run Switch

When the music calls for a change from one chord to another it is sometimes appropriate to play a bass run to segue from one chord to another. This is a specific set of four notes for each possible chord change called for by making the chord change two beats before the end of the measure when the first chord is ending and then pressing “Bass Run Switch” four times in a row during these last two beats of the measure. The Auto Bass selects the four appropriate notes automatically.

Stopping the Sound

Once a note is played it will continue until the next note is played even if no touch switch is pressed.  If no next note is played the note will die away naturally in about twelve seconds.

If you wish to end a note without playing a next note you can do so by pressing the Chord V and Chord VI touch switches simultaneously.

Key Change

Some musical arrangements will call for a key change somewhere in the song.  The most common shift is one full musical step up. This can be accommodated on the Auto Bass by pressing the “Key Shift” touch switch. Pressing the “Key Shift” touch switch again will end the key shift.  Repeated pressing of the “Key Shift” switch toggles the key shift feature on and off. The LED indicator on the top of the Auto Bass base is illuminated when the key shift is in effect.

Additional Features

“ON” Reminder

If no touch switch is activated for an unusually long period of time the Auto Bass will begin “beeping” intermittently as a reminder as a reminder that it is “ON”.  This function will stop automatically when any of the chord select touch switches is activated.

Low Battery Indicator

When the battery of the Auto Bass is reaching the end of its life the LED indicator on the top of the Auto Bass base will begin to flash rapidly, indicating that the battery should soon be replaced.

Foldable Fingerboard

To facilitate transportation and storage the fingerboard can be folded down by removing the fingerboard locking pin (see Photos).
