Upon analysis of my music, Liquid Notes throws up chord symbols that surely are not part of my music.

Last Updated: Jan 15, 2015 09:58PM CET
This article talks about Liquid Notes not showing chord symbols that match your arrangement after opening a project.

Quick Answer: Liquid Notes' harmonic analysis requires a 'clean' arrangement to show the best results. It may happen that other chords than expected are presented if no 'clean' arrangement is found. Read more below.
 

Liquid Notes and detection of chords

Liquid Notes' algorithms for detection of chords, etc. are only as 'smart' as a machine can be: in most cases the analysis is capable to detect chords with sufficient accuracy, granted you feed it with input data that enables the machine to correctly read it. Whenever this does not apply, Liquid Notes will display a warning or error message when opening a project - it's a hint that the machine can't read your input, which may lead to chord symbols not matching your arrangement.

This can be fixed easily normally, it helps to get an understanding of how Liquid Notes works. Read more below.
 

Understanding how Liquid Notes' algorithms work

When opening a project, Liquid Notes performs a track type analysis of your MIDI arrangement to detect the nature of each track. It looks for semantics used in the name of instruments and patterns in notes for each track to determine the type of track. The result of this analysis is shown to you in the Open Project Wizard, where you can make changes to the classification suggested by Liquid Notes before performing the harmonic analysis.

The harmonic analysis allows the software to read and interpret your MIDI arrangement from a composer's point of view: i.e. based on the results of the track type classification it is now capable to detect chords, correlations between single notes and chords, etc. over your entire arrangement. The results of the analysis lay the basis not only for representation of information on chords in the user interface of Liquid Notes, but also for chord recommendation and resynthesis as part of the reharmonization process.

While these are powerful features, they have limitations when it comes to understanding peculiarities in an arrangement us humans can detect with the mere eye. Hence, Liquid Notes relies on you as a trained composer to deliver a 'clean arrangement' for it to properly perform the harmonic analysis. 
 

Common problems leading to wrong detection of chords

Broadly speaking, a wrong classification of tracks and/or the absence of a clearly identifiable chord track is what causes a wrong detection of chords in most cases.

Find below also other related examples with information on how to resolve these problems and getting a better understanding on Liquid Notes' workings:
 
If neither of the above allows you to make changes to your arrangement in such a way that chords are detected correctly, send us your arrangement so we'll have a look at it and can explain why Liquid Notes is having difficulties with it. And, how this may be resolved.
