Getting Started

After launching Scor2 an empty list of chord progressions is shown. Press "+" in the upper right corner to add a new chord progression. A new chord progression "My Chord Progression" will be created and opened.

From inside the chord progression press "+" in the toolbar or the "Append(+)"-button to append a new chord. A picker view will be shown including the chromatic scale tones on the left and the harmonies on the right. Select the chord and press "Done" in the toolbar to return to "My Chord Progression".

Repeat the steps above to add further chords.

You can scroll the chord progression by left and right swipes. To select a chord tap on the chord, once, and a vertical bar will be shown before the selected chord. Multiple selections are not possible.

If you want to change a chord select the chord and press "Edit". If you want to insert a new chord between two existing chords select the successor and press "Insert". In order to delete a chord select the chord and press "Delete".

The App Functions in Detail

All chords of a given chord progression are shown on top numbered from left to right. All information concerning a chord is shown below the chord building a spread sheet. Information concerning an entire chord progression is shown in the header area on the left.

Keys and Miss Tones

The list of keys sorted by the number of miss tones. The key with the minimum number of miss tones is shown, first. Use this list to find the top key of a chord progression and to find which tones should be avoided when improvising on a scale.

Chords and Tones

All chord tones listed bottom up.


The chord functions of a given key.

The keys are shown as mentioned in "Keys and Miss Tones". The following table describes all possible functions and their symbols:

Related Chords

A list of chords which share the tones of the source chord except one tone at maximum. E.g. this list includes chord substitutes like Dm for F or Em for G. Use this list to find chords which might replace the source chord.


This list of chords might be suitable for modulations. The shown chords share tones and have additional tones with consonant intervals or half tones compared to the tones of the source chord. The idea behind is to use lead or slide tones to modulate to another key.

Consonant and Dissonant Tones (Cons/Diss)

The top key tones are listed bottom up. The first tone (1) listed per chord is always the most consonant melody tone played with the chord and the last tone (7) the most dissonant one. The tones below the top key on the left describe the consonant and dissonant tones over the entire chord progression. Use this list to find tones for melody improvisations.

Scales and Tones

All determined scales and their tones.

Please keep in mind that Scor2 is only a calculator. Finally, the ears decide.
