FOR PROFESSIONAL-LOOKING MUSIC CHARTS, 1CHART IS ALL YOU NEED
Create, share and print easy-to-read music charts with the only app that gives you all the power of the Nashville Number System, while also offering the flexibility of switching to letter-format chords whenever you like.
At the core, 1Chart is built around the Number System and all its shorthand flexibility for charting music. But why stop there?
1Chart is also built for those who prefer to read letter chords rather than number chords. “Am F C” or “6m 4 1”? The choice is yours. Now anyone who prefers letter chords can enjoy the Number System's concise charting advantages — without needing to read numbers.
Have a chart using letter chords and want to change keys? No problem. Select a new key, and your letter-format chart is updated to reflect the change.
CHART FASTER AND SMARTER
- Clear typography makes your charts easier to read
- Copy/paste measures or sections for faster charting
- View charts in your choice of three font sizes
- Share charts and notebooks as PDFs or editable 1Chart files
QUICKLY TYPE CHORDS

ABOUT THE NASHVILLE NUMBER SYSTEM
Nashville Numbers is an ingenious shorthand system for charting music that identifies chords by number (relating to scale degree) rather than letter, so charts are key-independent. A Number chart is valid no matter what key you choose to play it in.
Take a progression spelled with the chord letters, A, D, and E. In Numbers, these chords are written as “1, 4, 5,” matching their position in the A scale: A is first, D is fourth, and E is fifth.
Because scale relationships don't change when you change keys, “1, 4, 5” works in any key. Change the key to G, and “1, 4, 5” indicates you’ll want to play G, C and D — the first, fourth, and fifth notes of the G major scale.
Combine this flexibility with rhythmic and dynamic notation, and you’ve got a powerful format for creating concise roadmaps of songs for use when rehearsing or performing.
1Chart includes the option of showing chords in number or letter format, giving you the best of both worlds. You can easily toggle between number chords and letter chords at any time in any chart you create.
I downloaded this app to be able to write Nashville charts, as it was recommended to me as a friend. I am totally blind, and I use the built in screen reader on the IPad Voiceover. There are some things that I can access with the screen reader beautifully within the app, but other things such as some text edit boxes which are not labeled and also there are some unlabeled buttons in the app where Voiceover just says button. I feel this app could be very useable for a blind musician, and having complete access to this app would greatly help me in my job as a worship pastor. The app is almost there as far as accessibility, but there are a few things that I would need access to as a voiceover user to completely be able to use the app at its fullest. I would love to be able to talk to someone from the development team so that I can demo for them what is accessible and what would need to be made accessible. I was pleasantly surprised to see that I could interact with this app at all with voiceover and I would love to be able to add this app to my toolbox. Thank you so much for taking the time to read this review.

Alignment issue, please fix!

I’m a full time musician in Nashville. I play on Lower Broadway regularly and the number system is how we communicate down there. First let me say most of the features on this app are awesome. I would use it for everything but paper charts still have the edge because of ONE issue…when you do ANY slash chords, split measures, or add repeat signs it throws off the alignment of that line which is hard to read. The chords don’t line up with each other vertically down the chart. (You can even see it in the screen shots of the app on the App Store) Each chord on the chart should be squared up on a grid system. The jagged lines make this app borderline unusable for a high pressure sight reading situation. Yes, I’m aware of the “align measures” feature but that wastes valuable screen space and still sometimes doesn’t line up right when there are lots of changes or multiple columns. I need all chords (regardless of modifiers) to fit squarely on the screen with ONE page in TWO columns. This is especially important with songs that have a lot of changes and large arrangements. Other than that, everything else in this app is fantastic. If the developer fixes this issue I will give 5 stars and never look back to paper charts. Thank you

Hello and thanks for taking the time to post a review! Great to hear 1Chart is helping out on Lower Broadway! We appreciate your feedback on alignment. Although alignment in the app is working as designed, we also fully understand that it’s not meeting your needs. Sounds like an “auto-align, auto-column-width-adjust” feature is more in line with what you’re looking for. We’ll definitely take your feedback into consideration as we plan future versions of the app. Thanks again, and please feel free to contact us via the 1Chart website any time you have additional suggestions — or if you’d like to follow up further on this topic!
Awesome! Wish it had a few things though

I absolutely love this app and it has made charting and organizing my charts a breeze. However, I would love to see the following in a future update:1). Apple Pencil support. It would be awesome to be able to write on my charts directly in the app. The only way to do this is to export my chart as a PDF and save it elsewhere. I prefer keeping my charts within the app since the notebooks feature is super handy.2). The ability to import PDFs. I like to add snippets of tabs over some of my charts. Since the app doesn’t allow me to add a screenshot of anything to my charts, it would at least be nice for me to do it in another app and then import that new pdf back into the app for the sake of organization.

Thanks so much for your review and feedback, Franciquini. We've noted these requests on the wish list for future updates. Please let us know anytime you have other ideas for 1Chart!
Almost 5 stars!

These charts are clean, easy to read, and easily transferable to apps like ForScore where reading/marking is more practical. The app is also relatively easy to use. I love the app and I make every chart besides jazz tunes in this app. A few things that may make the app better:Make sharing charts with other people easier. The sharing/notebook creation process is pretty strenuous. There must be a way to make a highlight all button or make the selection process more similar to the Apple email app.Rhythmic notation: when you want to erase one rhythm, you have to erase all rhythms written for the selected chord. So if you write an 8th note when you meant to push 16th note, you have to erase all the rhythm you’ve written up to that point. Same goes for beaming - if you make an error beaming rhythms over multiple chords, you have to erase all of the chords and rewrite them with the proper beaming. Also, it is currently impossible to denote the number of beats for a chord if you are also trying to notate a push. I hope I’m wrong, or that there is an easy solution to these problems!Tempo/Style marking: there is no way to denote what note value gets the beat!! This makes the writer have to make a decision about how to mark the tempo in compound time like 12/8; do you mark the 8th note pulse or the dotted quarter note pulse? What if the song is in cut time? There should be a way to clarify this. As far as style markings: although you could use the subtitle for a style marking, it would be great if there was a text box in the upper left hand corner beneath the tempo marking where you could write the style of the song. Again, I love the app, and I hope that I’m wrong about these few issues and that I’ve overlooked how to get around them, but I think most users would agree that fixing these issues would take the app to the next level. Thanks!

Thank you so much for taking the time to offer your review and feedback! It’s great to hear you love the app, and we appreciate your suggestions for improvements! We'll take your ideas forward as we work on future versions.A couple of follow-up items which might help as you’re using the current version of the app… Rhythmic notation: You may already be aware, but it’s possible to tap “Undo” (the 180-degree back arrow at top left) to “delete” rhythmic notation or beaming that has just been typed. You can undo back through multiple steps if needed, and this will work to undo each character of multi-character rhythmic notation. Of course undo won’t work if you’re wanting to delete rhythmic notation that was saved in an earlier charting session, but we wanted to mention the undo option in case it simplifies certain scenarios for you.Also, please note that it is possible to denote a push & number of beats — you’ll want to use the 8th-note (or 16th-note) style push symbol for this (looks a bit like an 8th or 16th note with a tie after it). Then, after your push, you can tack on traditional rhythmic notation, hash marks, or dots to indicate number of beats.Tempo/style marking: Can you visit 1chartapp.com to email support about this? We’d like to understand more about what you’re trying to achieve here!Thanks again for taking the time to offer feedback, and please contact us at any time via support at 1chartapp.com if you have further suggestions or questions.
- When adding charts to a notebook, a new “Select All Charts” button makes it easier to create an exportable notebook containing all your charts.
- A notebook exported in 1Chart Notebook format (.1nb) now retains custom-sort info.
- Fixed a bug that could momentarily interfere with display of the header key after exiting Performance Mode.
