AltiChord is a chord dictionary and chord reference application for various stringed instruments like guitar, bass, ukulele, mandolin or bouzouki.
AltiChord supports more than forty-five chord types, both simple and complicated ones used in jazz music, including slash chords (Cm/G).
AltiChord uses sophisticated algorithms to produce the chord charts, which allows it to work equally well with both standard and custom instrument tunings.
In addition to the usual chord shapes, AltiChord lets you choose among more difficult chord shapes with two barres and big stretching between fingers.
You can display, compare and practice several different chords at once - may they be chords of a song or different variations of the same chord.
When you start typing, a pop up menu will appear, suggesting chord names.
The chord charts will appear as soon as you type a chord name.
You can reorder the chords by dragging and dropping the rounded tokens around.
Clicking on the white arrow next to the chord name will show a popup menu. From there you can edit or remove a chord.
You can also transpose the entire sequence.
Setting Up Your Instrument
You can select one of the predefined instruments and tunings by clicking on an instrument in the left column and then on a tuning in the right column.
Alternatively, you can define your own tuning by selecting 'Custom' instrument on the left, then the number of strings of your instrument and then choose the corresponding string notes and octaves from the popups below.
Limiting the Complexity of the Shapes
The application lets you filter the chord shapes shown.
You can limit the number of fingers used in a shape.
You can also limit the chord shapes to ones without barre, small barre only, big barre or two barres.
Stretching and Strumming
You can limit the finger stretching - no stretching, small or big (two frets).
The last option group lets you choose between different strumming and picking options: the chord shape must include all strings, all strings with possibly omitting few from the lowest, from the highest or allow any string combination (suitable for finger-picking).
You can sort the shapes by fret or by difficulty.
Listening to Chords
A 'play' button will appear when you hover your pointer over a chord diagram. Press it to hear how a chord sounds.
A chord can be played in three different styles: slow arpeggio, fast arpeggio or strum. The playback style used by the play button is configured in the preferences panel.
In addition, you can play the chord in any style from the application menu or using the corresponding keyboard shortcut.
A 'TAB' button will appear when you hover your pointer over a chord diagram. Pressing it will display a tablature view of the chord.
The first option group lets you choose between German and English notations.
The second option group lets you choose your handedness.
The playback style determines how a chord is played by the hovering play button. A chord can be played in any style from the application menu.
The next two options let you limit the number of muted or open strings in a shape.
Showing chord shapes in any inversion is particularly useful for instruments with few strings like ukulele or mandolin.
The last option group lets you configure how the chord shapes are copied to other applications.
On this page you can choose which intervals can be excluded from a shape, how many of them simultaneously and how many times a tone may repeat.
Each chord category (triad, seventh, etc.) can have its own settings.
There are four presets that can not be modified and a custom preset.
The 'Default' preset allows for some flexibility e.g. the 5th can be omitted from seventh chord. The 'Strict' preset forces all intervals to be present (except when the instrument does not have sufficient number of strings).
The 'Leave out bass' preset includes chords with the bass note not present in the shape.
The 'Default' preset limits the repetition of tones to some extent while the 'Legacy' preset corresponds to versions prior 1.7 that did not have this limiting feature and lets the tones repeat arbitrary number of times.
