ChordTouch for android

Format: Android devices
Pricing: Free
Description:
ChordTouch is a simple app for android which plays sampled piano chords. In a 2-step touch process, the user first selects the desired root note, and then selects a chord quality to hear the resultant chord. Within a given key, all 7 diatonic pitches can be used as root notes. To change the key, simply tap the white key button on the bottom right corner, and any of the 12 major keys, plus their relative minors, can be selected. The diatonic root notes will change accordingly.

A variety of chord options exist, including major and minor triads, all five seventh chord types, first inversion triads, a 4-3 suspension, and even 9th chords. Although it is tricky, chord progressions can be created and played by stringing together multiple chords, changing the root pitches accordingly. 

Features:
  • Chord generation in all 12 major or minor keys
  • Single tone mode
  • Ability to modify the chord layout

My Experience:
ChordTouch's key benefits are ease of use and a simple layout. Furthermore, the chord options included will cover and correlate with the vast majority of music that students hear and experience. The chords in ChordTouch are applicable to rock, pop, band, orchestra, and choral music among others. Only advanced jazz or advanced music theory students are likely to notice and be detracted by the chords not available in ChordTouch. The interface is very simple and easy to use: pick a root, pick a quality, and boom, you get a nice piano chord. Change the key if you want to. 

ChordTouch's simplicity is also its downfall. The piano sample sound is nice, but it gets boring and repetitive after a short period. This will be a negative for users of other apps that include the ability to change the output sound. A lack of octave transposition limits its functionality - low register singers or instrumentalists may find this a detracting factor. With all the keyboard apps available, ChordTouch's single tone mode is basically useless.

I would not recommend ChordTouch for any kind of performance or accompaniment situation. Although the interface is easy to understand, it does not lend itself to playing chord progressions quickly or smoothly. By nature, the two step selection process of root, then quality produces awkward transitions between chords, regardless of how much you practice or how fast you get. The video above is a good example.

Pros:
  • Simple, easy to use interface
  • Good variety of chords to choose from
  • Free

Cons:
  • Two step process is hard to do smoothly and quickly
  • Piano output sound only
  • Layout of diatonic root notes (purple buttons) does not change for minor keys
  • Cannot transpose octaves; higher octave tonic chord (built on scale degree "8") is unavailable
  • Difficult to figure out how to alter the chord layout

Final Thoughts & Verdict
ChordTouch could be a useful tool to aid in introducing or reviewing chords and their different qualities. It could be used for brief ear training exercises; the teacher could play chords and quiz students on their quality, or students could test each other. The app's limitations quickly become apparent, and I believe most users will find other apps that can do everything ChordTouch does, plus a lot more. 

However, since it includes so many chords students hear every day, the interface is simple, and its free, ChordTouch is at least worthy of mention to students. They may find creative uses for it (they could try to figure out and play the chords to their favorite pop song), and even if they only use it to play around in their free time, at least they will be thinking about and listening to harmonic functions.

With accompanying tenuto app

Format: Web browsers (for full website)
               iOS devices (for Tenuto and theory lessons apps)

Price: Free for web features
            $2.99 for the theory lessons app
            $3.99 for the Tenuto trainer and exercise app

Features:
Musictheory.net features interactive music theory lessons on topics ranging from the introductory (staff, clefs, duration values) to the more involved (keys, scales, and triads) to the advanced (inversions, chord progressions, and melody harmonization). The lessons allow students to work at their own pace and include audio and visual enhancements. Interactive trainers allow for practice and drill on a variety of skills, including note identification, scale, chord, and interval identification, key signature identification, ear training, and more. The difficulty and complexity levels for each exercise can be customized for each student or class.  

This resource is valuable to music educators as it it can benefit students at all levels of music education, from beginners to high school or adult learners. See the images below for an idea of the wide span of content covered on musictheory.net. It can benefit musicians in all performance mediums, as the theory concepts are universal. All of the features can be accessed for free on a web browser, and the exercises and lessons can each be accessed via their respective apps on iOS devices. 
Personal Experience:
I have been able to use the features of musictheory.net in a wide variety of settings. The lessons and trainers work well with beginning musicians as they are learning the fundamentals of music notation and note names. With more accomplished musicians, the key signature, scale, and ear training drills can further improve their skills. Students who need remedial work in music literacy can refine their abilities, even off to the side during ensemble class, with exercises tailored to their needs. I have used the exercises with beginning level and intermediate level students, and in both one-on-one lesson and full ensemble contexts. We turn it into games and see who can score the highest on each drill. I have also put exercises up on our classroom Smartboard, lined the students up single file, and had a "knockout" style elimination competition, which they get a kick out of. Several students have enjoyed the activities so much that they have put the apps on their own devices.  

The lessons are especially beneficial for any type of music theory class, as the concepts start at the very basic and progress to the fairly advanced. Even at the level of an AP Music Theory course, the lessons on www.musictheory.net can be a great asset to students for many of the concepts covered throughout the year. The drills in scale, interval, and chord identification and ear training are especially beneficial in preparing for the AP Music Theory exam.

Pros:
  • Lessons cover a variety of music theory concepts
  • Lessons are interactive - students control the pace, and lessons include both visual and audio depictions of concepts
  • Training exercises can be completely customized to any level of difficulty or complexity
  • Interface on all components is easy to use
  • Website access is free

Cons:
  • Lessons clearly demonstrate concepts usually in the key of C Major or a minor, however there is not always transfer to other key areas
  • Content that is available for free on the web site is not available for free on mobile devices
  • The mobile apps are limited to iOS devices. Users who enjoy the website features, but who don't have an iOS device, will be disappointed
Final Thoughts & Verdict:
www.musictheory.net is a GREAT resource for music educators at any level. It cannot provide an entire curriculum or an entire class worth of activities, but the lessons and trainers are fantastic supplements for any music class or lesson situation. The complete customization of any trainer exercise allows for each student to have an individualized experience, which is incredibly valuable. Music learners of all levels can find some sort of benefit with this resource. Even if students only need help with one concept, such as key signatures, a lesson or exercise can be found to accomplish the goal. Free access to the web version, uncluttered by ads and other junk, is an incredible value. Those who feel urged to support musictheory.net can pay the small app cost.
