Concertina is an easy to play, authentic sounding virtual Anglo Concertina in the most popular keys of C/G.
The instrument is bisonoric, meaning it plays a different note for each button depending on whether you are pushing or pulling on the bellows.
A C/G instrument has one row of buttons where the push notes make a C chord and on the other row make a G chord. The pull notes provide the scale tones between the chord notes. The third row on the right side of the app is used for additional accidentals not found in the scales on the other two rows.
The C/G tuning is the most commonly used when playing tunes with other instruments like fiddles, flutes, and whistles in their standard D tuning.
To play, simply tip to the left for a bellows push note, or to the right for a bellows pull note, and press a button. The PUSH/PULL display shows which direction the bellows is moving.
Touch the "?" icon to show the note names.
You may reverse the bellows while pushing a button simply by tipping in the opposite direction.
Touch the "i" icon to show the settings where you may adjust the tilt sensitivity, push/pull tilt direction, and right-side chromatic row configuration.
Here's the best way to hold the iPhone for playing:
Support the iPhone between the top of the palm on the left and the thumb and little finger on the right. This allows the fingers to reach all the buttons. The iPhone can face up or away from you.
On the left hand,the closest buttons are played with your left index finger, the next farthest with your middle finger, the next farthest with your ring finger and the farthest with your little finger. On the right, the closest buttons are played with your right index finger, the next farthest with your middle finger, and the farthest with your ring finger.
Up to five buttons may be pressed at the same time to play chords.
The button layout is based on a 17-key modified Jeffries style for playing traditional Irish dance tunes in the most common keys.
