Making Just Intonation Play Along Tracks for Your Performing Ensemble (Using Tonal Energy and GarageBand)

There are a few things that would be helpful to know about my music teaching philosophy before reading this post.

1. I believe that tone production, intonation, balance and blend are central to teaching performing musicians. I prioritize them much higher than fingering technique, rhythmic precision, and even reading comprehension.

2. The way I structure my band classes starts with, is focused on, and always revisits those core ideas.

3. I have accumulated a vast variety of tools and teaching strategies to meet my goals of having superior tone quality, intonation, balance and blend. One of the most essential tools I use is the Tonal Energy Tuning app.

Tonal Energy Tuner

What is Tonal Energy? A hyper charged, power-user app for musicians that has many advanced features, including...

- Tuning drones that can be triggered polyphonically

- Feedback as to how in tune a performer is, which includes a delightful happy face to depict good or questionable intonation

- Drones and feedback can be adjusted to different temperaments

- A metronome (with more features than nearly any alternative on the App Store) that can be used separately or at the same time as the tuning drones

- Analysis tools that depict amplitude and intonation on an easy to read visual graph 

- Recording and play back practice tools for musicians to listen back to their performance

- Automated metronome pre-sets that can be sequenced 

See the video below. I will first depict the tuner playing a Bb drone, then I will show how it can model a Bb major triad all at once. Then I will turn the tuner to just intonation mode, and you will hear that the third and fifth of the chord are appropriately adjusted so that they are in tune with the Bb root. Next, the video will demonstrate how the metronome can be used in combination with these drones.

Imagine now that a student is playing a scale along with Tonal Energy. By leaving the tuner in just intonation, and centering around the key area of Bb major, every note of the scale that I touch will resonate accurately with the Bb, giving the student an accurate reference to blend into.

Developing An Inner Ear for Diatonic Intervals

Much of music is made up of scales. For a student to learn how to most accurately tune different intervals and chords, I have the drone running in the background during most of my teaching in whatever key area we are working in. I then move my finger to the correct notes of the melody to model and reinforce what good intonation would sound like. See below for an excerpt of a song my beginning students might play.

In the video below, watch as I play this song by dragging my finger along to the melody. This happens with a metronome to reinforce the beat. I like that TE has the option to speak counts out loud. In my experience, this really reinforces a concept of strong beats, weak beats, where in the measure the performer is. Other tuning apps have the counting feature as an option, but the sounds in TE sound more natural and less computerized.

Making Play Along Tracks in GarageBand

As you can imagine, I am doing a lot of dragging my finger along while students play for me. This gets tedious. I also want my students to be able to hear these pitch relationships when they practice, so I have begun recording them into play along tracks. How do I do this?

Inter-App Audio Apps and Audio Extensions in GarageBand

In the iOS GarageBand app, audio input is usually performed using either software instruments or by recording audio directly into the device with the microphone. But what you might not know is that you can also create a track that is based on the audio output of a third party audio app. If you have ever used a DAW, think of Inter-App Audio Apps and Audio Extensions like plugins. Once launched, you are kicked into a third party interface (much like using a reverb plugin from Waves or a synthesizer from Native Instruments) which then adds to or alters the sound of your overall project. In a more recent GarageBand update, Apple categorizes Inter-App Audio and Audio Extensions under the External option when you create a new track. 

Audio Extensions are effects that alter your tracks like reverbs and EQs, while Inter-App Audio captures the audio of a third party app and records it into its own track in GarageBand. You can browse the App-Store for Audio Extensions that work with GarageBand. 


Recording an Inter-App Audio App Directly Into A GarageBand Project

Watch in the video below as I set up an Inter-App Audio App track with Tonal Energy. What I am going to do next is press record, and record my justly in tune play along of Lightly Row into my GarageBand project. I will do this using the euphonium sound. The euphonium drone is one of the roundest, darkest, and fullest sounds, while also containing a great range, so it is effective for most instruments to play along to while also modeling a rich, full, resonant sound.

Accurate Note Input with MIDI Controllers

In this video, you can really hear how sloppy the transition from one pitch to the next is when I drag my finger. Notice also that I did not play repeat notes. It is difficult to play the same pitch twice in a row without Tonal Energy changing itself to that key area. One way around these challenges this is to set up a portable MIDI keyboard with Tonal Energy. The one I have settled in is the CME X-Key with Bluetooth.

It has a sleek look, is very small, and has low key travel. It has buttons for pitch shifting and octave jumping. And Tonal Energy adapts to it in just intonation mode! Watch in the video below. As I change which chord I am playing, TE automatically snaps the third and fifth of each triad in tune, relative to the root. For my Lightly Row performance, I can now hold a Bb drone on in one hand, while playing a melody in the other.

Embellishing The Track with Other Instruments

The resulting play along track is alone pretty useful for students. Let’s make it more fun by adding a drum track.

We can make it even more fun by embellishing with bass and other instruments. I like to change up the style of these play alongs. Sometimes I don't even pre-record them, I just improvise along with my students to keep things fresh. Be careful though. These software instruments are NOT justly in tune, so too many of them can defeat the purpose. I try to combat this by having the drone be the loudest thing in the mix. Notice in this recording I have tried not to create any motion in the accompaniment that interferes with the consonant intervals in the melody, so that the listeners ears can remain focused on the drone for their reference.


Well, that's it! I can trigger these in rehearsal, sectional, and even share them with my students for home practice. Regular practice with tuning drones has really turned around my band's sound, and gives students the foundations for long term ear skills that will help them to HEAR what is in tune, not just respond to the commands “you're sharp!” and “you’re flat!”

iOS apps I would love to see come to the Mac, a musician’s perspective

There has been a lot of buzz lately around ‘Marzipan,’ a set of developer tools that Apple is making to help third party developers more easily port their iOS apps to macOS. It is heavily rumored that Apple will detail this initiative at their developer conference, WWDC, this June (during the keynote on June 3rd).

Last year at WWDC, Apple unveiled four Mac apps that use this new set of tools to bring iPad-like versions of iOS apps to the Mac. The apps launched were Home, Stocks, Voice Memos, and News. The apps have been met with much criticism for their lack of Mac-likeness. For example, when you double click a news article in the News app, you can't see an article in a separate window, a behavior you would expect from the Mail app or Notes app on Mac. Likewise, the Home app, when setting up a time based automation displays they iOS style date picker, with scrollable numbers, rather than the calendar like interface that you would see when selecting a date in traditional Mac apps.

I agree that these four Mac apps are garbage, but I would much rather have the utility of them than not. Even if all these Mac apps do are act like iPad apps that accept input from a cursor instead of a finger, I would still kill to have any of the following on macOS:

-Tonal Energy Tuner. There are no tuning drone based apps, even on the web, that do 1/100th of what this iOS app does. My Mac is my primary device for sharing audio and visuals with my students during class. This would get used every single day.

-forScore. I have a weird way of managing my digital sheet music using the file system of my Mac, but then importing duplicate copies into my iPad’s forScore library. It would be really nice to have one place where this is all managed across all devices. Of course, this would require forScore to sync a library across devices, which the team has told me is too difficult a task to prioritize currently.

-Twitter. Twitter killed their Mac app recently and as someone who recently started using their app on iOS (Tweetbot is still far better but Twitter no longer provides the proper APIs for them to stay up to date on modern features), I would really prefer to not use the web browser on the Mac.

-Apollo. To my knowledge, there has never been a good Reddit client on any non-mobile device. Apollo is great.

-Facebook Messenger. I hate Facebook but it is a necessary communication tool. I would love to use it for that without going to their stupid website ever again.

-Overcast. My favorite podcast player. Would love to have it on Mac.

-Health. An app that excels in showing me data on graphs and charts sure would be useful on the big screen of a Mac.

-Due. My favorite reminder app is already on Mac but it looks gross.

-Instapaper. I use ReadKit on the Mac as an Instapaper client on Mac now, but would not mind something more minimal. Instapaper is the perfect candidate for a Marzipan app for its simplicity.

-Instagram. Who wouldn’t want this on Mac?

-Tempo. There is only one good metronome app on the Mac (Dr. Betotte). Opening up UIKit to Mac developers would bring a whole lot of competition in this space. Frozen Ape’s Tempo would be my first choice to get ported over.

-AnyList. Their Mac app is already just a gross port of their iOS app. Using Apple’s tools would surely make it prettier and more responsive.

-Ferrite Recording Studio. My podcast audio editor of choice is only on iPad. It sure would be cool to use these tools on a bigger screen with keyboard and mouse.

Favorites of 2018 - Apps!

These posts will never happen if I don’t make it fuss free. So here is it! With little introduction or fanfare, the ‘stuff’ that made up my year. My favorite albums, live shows, apps, and ‘things’ of 2018.

Next up, apps!


Things and OmniFocus

Task management software makes up about 50 percent my time on computing devices so it’s natural that I include what I consider to be the best two apps in this field. After seven years of using OmniFocus, I am experimenting with Things again. I plan to write about this switch in more detail but for now I leave you with this: if you are looking for a powerful way to stay on top of your tasks and don’t mind paying for a premium design, check these apps out.

The Today view in Things displays all of my tasks for the day alongside my calendar.

The Forecast view in OmniFocus is similar to the Today view in Things. Though I have it turned off in this screenshot, it actually displays your tasks inline with your calendar events so you can see where ‘due’ tasks fit into your day.

The Health app by Apple is my hub for collecting all sorts of data about myself from various devices, apps and clinics. It houses data from devices like my Apple Watch, Spire respiratory monitor, Fitbit WiFi scale, and Spark Smart Water Bottle. It tracks data in third party apps like: work outs, active calories burned, steps, heart rate, sleep, water intake, nutrition, meditation minutes, caffeine intake, and blood pressure. It can now even aggregate health data from participating clinics and practices so I don’t have to log into a million web portals. My Quest and LabCorp results are a tap away. The beauty of the app is that it allows me to organize these data points and see them alongside one another so I can draw meaningful conclusions about them. Like for example, I eat better on days when I get more sleep.


Apple’s Home app is the hub for controlling my smart home. I can control all of my smart things in the same user interface rather than by punching into lots of different apps. I can also use it to automate different actions. For example, my Good Morning scene automatically runs at 6:30 am every day which turns on my lights, changes the temperature, and lately, turns on the Christmas tree.

My Today view in Apple Health aggregates all of my health data regardless of which app is responsible for tracking it.

Tonal Energy Tuner

Absolute must for an instrumental music teacher. Using the new Screen Time feature on iOS reveals that I spend too much time on Reddit. But also that I spend more time than any other app in Tonal Energy. It’s literally running in the foreground all day long while I’m at school, helping students to match pitch, blend, and keep steady time.


This may be my productivity discovery of the year. Trello is the team project app you have been waiting for. It’s vibrant, Kanbab board style interface will have your team, family, or Dungeons and Dragons group enjoying every minute of collaboration. Bonus points for how well this app integrates with Slack which is my preferred team communication tool.

Planning concerts in Trello allows my team to share todos, check lists, files, and more. We can give items due dates and even assign tasks to other members.

GoodNotes has become my go-to handwritten note application. It acts like a bookshelf of notebooks so to speak. I take a lot of the work I create in iWork, Ulysses, and OmniGraffle, export them as PDFs, organize them into notebooks in GoodNotes, then annotate them on the go using my iPad. My favorite thing to do with it is keep a notebook of seating charts that have my rehearsal annotations on top of the names of my students. I love how you do not need to trigger an annotation mode to start scribbling on a document with the Apple Pencil. It just feels like paper.


There are a lot of great habit building apps out there but Streaks has stuck with me because it encourages you to focus on just six habits at a time. When I am building too many habits at once, they start to feel like a todo list. The Streaks method of choosing six, along with its addictive user interface, keep me launching the app, which keeps me working towards my goals.

AutoSleep and AutoWake

Of the ten or so sleep trackers I have tried for the iPhone and Apple Watch, AutoSleep has stuck with me the most. There are numerous things I like about it, but most of all is how it figures out the most accurate number of hours I have been asleep whether I wear my watch to sleep or not. The companion app, AutoWake, wakes me up silently with haptic feedback on the watch. It does this when I am in my least deep sleep within a half hour before my alarm is set to go off. This eases me awake rather than jolting me awake. I plan to blog later this month about how I am automating some cool stuff in my house when I wake up using this app.


WaterMinder is my favorite app for tracking water intake, mostly because of its well designed and space efficient widget.


I did not get as much out of the Siri Shortcuts app this year as I wanted to. In fact, I had a lot of bad luck with it. But it is still an app that is working really well for me in a couple of small areas. In one tap, it generates a clean copy of my band's seating chart in GoodNotes for annotations and opens my lesson plan for the day in OmniOutliner.

CARROT⁵ Weather

This is my favorite weather app due to its clean and appealing design. It gets my pick this year because of how they continue to innovate the Apple Watch app. My favorite feature of the watch is the customizable complications. Carrot makes the best weather complication for the Apple Watch, maybe the best complication, period. Carrot allows infinite customization for how it looks on the watch, depending on which watch face you like to view it, and even in which corner of the watch face you prefer to keep it installed.

The Carrot Weather app complication can be seen in the lower left corner.
