Have you (or maybe one of your friends) ever wanted to learn to transcribe or play music by ear? It is so important for a musician to know what you are hearing. A good musical ear helps when you are composing, improvising, transcribing melodies, or playing with others. Most likely you have already tried different programs to learn to recognize intervals or even to acquire perfect pitch. However, although such programs develop your ear, but can you actually play any melody you hear as soon as you listen to it? Imagine you could understand music... It is like when somebody is talking to you, you not only hear pleasant sounds, but you recognize words and their meaning. One day I came across Alain Benbassat's program called "Functional Ear Trainer" and have been using it ever since. It is based on Alain's method to learn to recognize tones. The main difference between the Functional Ear Trainer and other methods is that it teaches you to distinguish between tones in the context of a particular musical key. You begin to recognize the role (or function) of each tone in this key, which is incredibly similar to its role in other keys of the same scale. And it is *guaranteed* anyone can gradually develop this skill. It does not matter: - who you are - an absolute beginner in music or a virtuoso professional musician; - how old you are - a 3 yo kid or a 90+ adult; - what musical instrument you play (you don't even have to play one). The only requirement is to practice for 10 minutes a day. I was so excited about this ear trainer that I have developed a mobile app based on the Alain Benbassat method. I hope you will find it useful.

Yet another ear-training app? Well, this one is different! Playing jazz, pop and improvised music means being able to quickly recognize and replay what you hear. Although this app began as an ear-training tool for students of jazz and pop at the Zurich University of the Arts (ZHdK), it is also intended for musicians playing in other styles, and at all levels. It was developed by Swiss IT specialist and jazz trumpeter Daniel Schenker, professor at ZHdK, in collaboration with his son Elia. How it works The app offers a host of ear-training exercises, many of them quite enjoyable, all designed to enhance both active and passive hearing. Active hearing means reproducing what you have heard on an instrument or with your voice, while passive hearing refers to the ability to identify such things as the scales, triads and four-note-chords, tensions and slash chords, on which active hearing is based. One of the features that make our app so special is the fact that its microphone enables a sort of dialogue between the app and the musician – whether on voice, brass and reed instruments, guitar, piano or electric bass. Unlike other apps, this one uses an integrated voicing generator to ensure that the chords played (position, voicing) correspond to the actual performance situation. In addition, the app uses a detailed educational guidance system, which allows users to individually customize the exercises. You can obtain over 280 achievements. Compete with other users and publish your high scores and trophies!   Active exercises (microphone) - Five-tone range imitation, major and minor: suitable for younger students or amateurs - Diatonic imitation: reproduction of notes in a particular key, vocally or on an instrument - Atonal imitation: improvement of relative or referential hearing - Tone sequences (2 - 6 tones) - Intervals - Resolution game: technique for the improvement of downward interval singing or playing - Bass imitation exercises: double bass notes and root notes of various chords are to be reproduced vocally or on an instrument, a central skill that is often underdeveloped - Sing or replay chord tensions (e.g. #9, b13) - Scales sandbox: imitation practice in tonal spaces from over 40 different scales - Tonal memory game   Passive exercises (identification practice) - Intervals / Interval series - Triads/four-note-chords in root position and inversion; top note positions - Four-note-chords with one tension (17 types) and with two tensions (15 types) - All 12 major and minor triads above a root note (slash chords/hybrids) - Identification of scales, modes and over 140 jazz, pop and classical chord progressions Depending on the setting, the chords can also be played arpeggiated. The app supports Bluetooth MIDI (iPhones only).   For whom is the app intended? - Singers both amateur and professional who want to incorporate (noteless) ear training exercises into their practice programme. - Musicians in primary and secondary school, musicians and singers preparing for university entrance exams (practical theory), and conservatory students - Musicians and singers of all genres, especially jazz/pop/rock, who want to freshen up or expand their chord vocabulary - Brass players: control in mouthpiece exercises (buzzing)

Verdict

The call

The clearest difference is price: Functional Ear Trainer at Free against ET's $5.99. Functional Ear Trainer also leads on ratings volume (3.7K vs 2). ET's advantage is in-app purchases (none vs 1) and update cadence (every 2 months vs every 7 months). On rating, ads and device support there is nothing between them.
