Great musical tool! Plus two suggestions

Tonaly has been the perfect tool for me to start messing around with chords. I’m fairly new to music theory but this app makes it really simple and quick to navigate. The UI is really clean and works perfectly. For anyone wondering if the price is worth it, in my opinion absolutely. If you are looking for a quick and easy way to make chord progressions, or a more advanced tool to help you write your song, Tonaly can definitely help!

My only two suggestions are an option to have the chords play in different octaves (without auto inversions having to be on). When I want to listen to a higher octave I have to turn on auto inversions, which is a feature I love but I don’t always want to use it.
My other suggestions is for the chords outside the current key to still have a Roman numeral to show how they relate to the original key. (For example showing Cm as i, when the project is in a key of C. Or C# showing as bII, at least I think that’s how it would be written. I’m still learning! 😂

Wow, that's great to hear! I'm glad that you're finding Tonaly to be the perfect tool for you and your music journey.

Thanks for taking the time to share your suggestions with me. I appreciate your feedback and I'll definitely keep it in mind as I continue to improve Tonaly. Your suggestions for the octave options and Roman numeral labeling outside the current key are definitely valid, and I'll make sure to consider them as I move forward. Especially octaves is a thing that might not take too long to join the app.

Thanks again for your review!

Fun and super helpful for writing songs!

Great little app, very helpful for composing and actually hearing chord progressions back for those who don't have relative and perfect pitch. The only thing is that I would love for more customizations of the chords, namely inversions (even in combination with four note chords) and different rhythms that aren't 4/4. Right now, the root of the chord is always on the bottom. Inversions add a different color to the chord and are very widely used in songs and compositions. Some chords in the context of a certain progression just aren't the same sound without inversions. As for rhythms, it would be helpful for more control over how many bars a progression is and how many beats are in a bar. Right now, it's always 4 beats to a bar. Either 4 or 8 bars. I don't think adding different time signatures would be incredibly difficult nor adding custom length of bars any amount between (2-8). Also, adding chord changes within a bar would be awesome. That would add more complexity, sure, but the app for have so much value for making fully realized chord progressions for a song or composition. Other than those things, a solid app with lots of potential for improvement. I'm sure the inversions and rhythms features can be included in a future update.

Absolutely Brilliant (two suggestions, though)

Hats off to the developer(s). This app is so well thought out and designed. I’m absolutely in love with it. A great tool for learning, songwriting, and deconstructing popular songs for making your own arrangements.

One thing I’d really like to see added is more in depth archive options when you save songs. I’m in the process of building out covers I know and would love the ability to tag songs to a genre, artists, etc. and be able to type in a search bar to jump right to it. It would also be nice to be able to add custom text fields above song parts. If I could just type in the first line of lyrics for versus, choruses, so on that’d be awesome. Then this app will be dang near perfect! 🤙

There are options to export out to PDF lead sheets so you could still use this app as a tool for building a good archive system yourself, but the app design and functionality is so beautiful I don’t wanna leave it.

Awesome! Thanks for your review! I'll keep your suggestions in the back of my head for future updates! Stay tuned!
