Klimper is a mobile music studio with built-in music theory to spark your creativity and speed up your workflow.

Find Chords that Work

In the chord palette your can explore chords that are available in your selected scale. While a chord is played, related chords are highlighted so you can easily find chord sequences that progress smoothly. Once you found a nice chord sequence, you can drag and drop chords into your song to build your composition upon it.
If you want to start your song with a melody and find a suitable chord progression, you can do that just as well: select notes and tap the search icon to show chords that match your melody fragment. It's real fun to experiment, seeing how different harmonic contexts affect the perception of the same melodic fragment.

Create Beautiful Melodies and Flowing Chord Progressions

In the piano roll, notes that are in harmony as well as the chords' root notes are highlighted. This makes it super easy to create leads, arpeggios and basslines and to experiment with different chord voicings to let your chord progressions flowing nicely.

Intuitive Editing

A simple, yet feature rich and context-aware user interface helps you build up your ideas into whole songs:
Group sections into song parts and arrange them via drag and drop.
Duplicate, copy and paste, playback selected notes.

File Export

Export and share your creations with audio file export.
Edit your song in other Apps with MIDI-file export.

Great app, could use some more things

I love the chord progressions that you can make with this app. It shows you chords that work best with each other so I can make chord progressions much better than what my tiny brain can make ;) anyways, this app would be perfect 5 stars if it had some more features. For example: more instruments, a swing rather than simple on the beat time, half steps rather than only using notes in the key, things like these. I would still recommend this for any music lover! Worth the money!

Exactly what I need

I have been searching for something like this to replace my piano apps and voice memos. I am a composer and spend most my time writing in my studio; however, I needed a quick way to record ideas and compose snippets on the go and at the time an melody pops into my head. Instead of singing, humming into a voice memo or playing my piano app and trying to memorize the part real quick. Anyway, I would only suggest to the dev to add a more practical way of changing tempo and making an option for triplets at a smaller level. You can write quarter note triplets but nothing smaller, forcing you to redesign your note layout, and adjusting the bpm. Regardless, this app is still a perfect app for what I intend to use it for but I could see it being very limited if people were to use it as a platform for full composition.

Too Primitive

The chords are given only in basic diatonic scales with 0 ability to explore outside of it. This isn’t much better than sitting at my keyboard and playing all the white keys in thirds (hitting the “transpose” button to get different key centers).

The sharps and flats are straight up wrong for many of these. Why is it showing me “G#” and “A#” for C minor? C minor is a three flats key. This isn’t hard to program correctly.

My last beef is that the chords are played in the most clunky, uninspired voicings possible. Basic root position, in thirds, no spread whatsoever. This app could be so good if JUST THIS was fixed. Give it a bass octave, spread the extensions to the higher octaves, voice things in fifths and fourths, etc. There’s also 0 voice leading from chord to chord, which adds even more to how primitive it sounds. There’s no harmonic motion.

Even without letting you escape the diatonic scale, voicing the chords to actually sound good would be way cooler for iOS music production. You already have stored all of these extended chords; just spread their voicings out, and employ some basic internal ability to voice lead even just the extensions.
