3 steps to play better solos


1. Editor

type in your chords
Type in any chord progression via our intelligent keyboard. We developed it from scratch to be very fast and easy to use.


2. Harmonic Analysis

algorithm analyzes the chord progression
Fed with the complete knowledge of music theory, our algorithm understands the math behind music. It calculates the key(s) and harmonic functions of the chords.


3. Analyzer

Get results for your improvisation
Start jamming to your chord progression. loreical suggests fitting pentatonics, scales and arpeggios. Change the results with the “configurator” to make it more challenging or easier.


Superior Improvisation

Dear guitarist,

guitar-player and fretjunkie

Are you eager to improve your improvisation skills? Increase your scale repertoire in a “hands-on” way? Learn how music theory and harmonic analysis works in action? Just type in the chords of a tune you want to improvise to. loreical will show you which pentatonic, scale or arpeggio you can play at what time in the tune. The knowledge of years and years of studying music theory is now at your fingertips.
Your improvisation will improve on the spot and your audience will hear the difference in your play immediately!
Create your songs with loreical or import your songs from iReal Pro to get your very individual analysis whenever you need new inspiration. Speaking of new inspiration: With the configurator-feature you can change how the algorithm works. Let it focus on optional notes to get more unusual results or favour certain scales that you like to use in your solo.
Your chord progression can be played like a backing track. Instantly start jamming and set a loop to work on a specific part. If you want to look up the fingerings of a pentatonic or scale just tap on it.
And if you want to know why something works so well, you can find the rules of harmonic theory applied to your piece explained in the help section. We call that: „reverse learning“. Improvise right away and learn afterwards what you just did. And yes loreical does look at the chords in context of the tune. It’s a real full-on calculation and not just giving you one and the same solution per chord.

Try loreical, have a play and improvise superior – now.




The algorithm has 3 modes. It can focus on convenient playing, guide notes or optional notes. You can keep it simple or spice things up with more challenging results.


Scale Selection

Activate or deactive pentatonics, scales or arpeggios. Only minor pentatonics? Every church scale? Arpeggios? It’s your call. Combine and create impressive solos with unusual approaches.



Use the playback function to instantly start jamming as to a backing track. The analysis is displayed during the playback. You can loop certain parts and change the tempo to nail down tricky sections.

Guided Tours

Take a tour through loreical and get a tutorial-like introduction to all its features. For example change one chord in the middle of your chord progression to see what happens to the analysis.


Change Key(s)

Sometimes the key detection is debatable. Just tap on the key to change it to the parallel or any other one. This is also useful to get new improvisation approaches and play solos in different colors.



We developed the chord input section from scratch. Easy to use. A no-brainer. Enter chords with our intelligent keyboard in no time.



Get suggestions for your improvisation and start your solo right away. Our algorithm calculates key(s), harmonic function, pentatonics, scales and arpeggios.
