Designed and created by Blake Kearney. Please see our video for detailed information at: https://vimeo.com/220089866. Clear Pitch explains and teaches perfect pitch, also known as absolute pitch. A user can expect to develop absolute pitch using this product, as well as improving other pitch coding abilities such as pitch memory, perfect piano and relative pitch. Clear Pitch is suitable for children, adults, musicians and non musicians. Anyone can use Clear Pitch for its cognitive and tonal benefits. The mechanics and algorithms of Clear Pitch are complex, but the usage is simple: Just press play and listen. You will develop better clarity in pitching and tonal hearing, and you will find your musical ability related to hearing will improve dramatically. Perfect / absolute pitch ear training is explained clearly for the first time so you will learn and understand: 1) What it is, 2) How it works, 3) What you are trying to achieve,  4) How to achieve it. This approach is entirely different to all other products that attempt to 'give' a user perfect pitch but provide no explanation as to how the brain actually processes and learns the skill, and no system to do so. Clear Pitch is the final chapter in ten years of academic research and vast quantitative and qualitative research, and includes the application of the findings of academics such as Dr. Daniel J. Levitin and Professor Diana Deutsch, leading exponents of absolute pitch theory. In short, Clear Pitch works differently. In our research of all perfect pitch applications available they divide into three types: 1) Most (99%) are simply testing devices to see if you have the ability and with the hope that the user may possibly improve with repeated testing. 2) A few attempt to guide the listener toward hearing the unique quality of a pitch with claims that some pitches sound 'twangy' or 'mellow'. This approach is interesting but has no labelling component and consequently hasn't produced any convincing results. 3) The third group uses mnemonic cues such as colours to hopefully stimulate recognition of the chromas. This is probably the closest match, but is too esoteric and still doesn't institute the simple labelling required. When you hear 'C' you want to think 'C', not 'blue'. All these systems overlook the actual mechanism required to develop the ability, which is the neural installation of a C.L.R. or chroma-label relationship. A C.L.R. is a neural association between a pitch and its name. Clear Pitch installs a C.L.R. in memory. CLEAR stands for Chroma Label Encoding and Retrieval. A chroma is the sound colour of a pitch, and a Label is it's name. Encoding means to learn, and Retrieval means to remember. Clear Pitch is a chroma labelling system which results in a user being able to identify the name of all chromas or pitches in the chromatic scale by sound alone without reference. This is perfect pitch (absolute pitch / A.P.) Clear Pitch contains a tutorial and on board instructions throughout the application of learning algorithms, that will explain and create a C.L.R. as you listen, and which leads to the perception of musical notes along with their names, or to be able to name a pitch without reference. The C.L.R. is installed via mnemonic memory devices called tonal linguistic cues that stimulate the association of the chroma and its label. T.L.Cs are delivered via 4 central modes: Active Encoding, Passive Encoding, Active Retrieval, Passive Retrieval. Encoding creates the C.L.R. going in to your mind and retrieval stimulates the C.L.R. going out. Passive modes don't require any particular attention so you can listen while day dreaming or sleeping. Active modes are most effective when used interactively, but can also be listened to passively. There is simply nothing available to date that comes as close to effecting absolute pitch as Clear Pitch does. Happy pitching with Clear Pitch. ## Key features - Develops perfect pitch (absolute pitch) - Improves pitch memory and relative pitch - Explains what perfect pitch is and how it works - Teaches how to achieve perfect pitch - Unique chroma-label encoding system - Suitable for musicians and non-musicians ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Professional Unlock | $7.99 | one-time | ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/clear-pitch-perfect-pitch-pro/id1244422910/reviews.md ### 2/5 — The sound quality hinders this good idea *2022-08-09* Hiring or just asking someone with high pitch sensitive and a good ear to help choose or design sounds would make this a much more powerful and effective app. As the pitches are slightly off, you can’t learn as well as if they were better made. Great idea but still needs work. **Developer response:** Thank you for the feedback regarding the vocal synth sounds. I used Yamaha’s proprietary Vocaloid software because computer generated voices are perfectly in tune and time. However, I agree they don’t sound good enough and I am updating soon with real human voices. If it is the piano you don’t like it is a generated Yamaha piano sample and probably the best timbre to work with. Softer more pleasant sounds are not as effective for cuing our memory to chromas. I will see what I can do to lessen the sibilance issue but whenever two melodies occur simultaneously and one is a human voice it can be problematic. Please let me know if this covers your notes in this area. Regarding the functionality and PR2 mode, this is sup­posed to oc­cur. PR2 ac­ti­vates once all oth­er modes x chro­mas have been heard, then it stays locked on PR2 un­less you re­set. There are sev­er­al rea­sons for this for­mat, but you can con­sid­er all oth­er modes as im­por­tant prepa­ra­tion for PR2, so once cov­ered you may get the most ef­fec­tive­ness from a long PR2 cy­cle. However, manual mode exists so that you can configure any mode to loop as you wish, or you can reset the app and skip through to any area you want. Please let me know if I have mis­un­derstood anything or if I have addressed your queries. Cheers, Blake Kear­ney ### 5/5 — you can feel it training your brain *2022-03-10* if you listen closely, you’ll learn. it’s that simple. **Developer response:** Thank you, I appreciate you understanding and identifying the premise of the system. Listening and observing how the sounds begin to self organise in the brain is fascinating and is all that is required. The complexity is behind the scenes so that the listener just needs to listen and allow the various sound combinations to form the neural relationships. If you have found the system to work for you, please feel free to contact me for research and pre release material. Regards, Blake Kearney ### 5/5 — Awesome and fun *2020-05-08* Awesome and fun. I feel like I am learning, and working with it everyday. I love the little catchy tunes. I get back with results! **Developer response:** Thank you, it is awesome and fun learning perfect pitch so I'm delighted that my app reflects that. The tunes are fun right. It took a long time to create them because they needed to be both 'tune like' but also algorithmic - the tunes contain the code that instructs the brain to connect the sound data. ### 5/5 — What a great idea! *2020-03-10* Although it’s early, I’m already noticing progress. Outstanding customer service. Very excited, will check back later. ### 4/5 — Needs more sounds... *2019-11-28* Starts with just piano sounds needs other instruments to further testing the ear with. also maybe expand the octaves toward the extremes on the piano...it is only two octave range...also be nice to have sheet music for the 12 songs...so far I enjoy it just wish you could change to saxophone or flute or some other instrument... **Developer response:** Thanks for the observation. Could you let me know if you have attained full recall of all 12 chromas? I do have multi timbral versions with a wider range but the system uses timbral consistency for mnemonic reasons and it is important users don't skip ahead until they have mastered the 12 pitch classes. I am happy to share the current research with you, and if you are hearing all 12 chromas there is a research program you may be interested in. Cheers, Blake Kearney ### 5/5 — Well made and thought out *2019-05-11* Very good user interface and experience is unique. Like the science oriented approach to ear training. Intuitive and pleasant to use, looking forward to more apps like this one. ### 4/5 — Best way to improve AP out there *2019-02-18* I took an interest in absolute pitch (AP) many years ago. I invested in an audio course and managed to develop AP for a few notes. I was never able to expand my hearing to all the other notes. This software uses all the tricks available to improve your AP. It is largely a passive exercise so you just have to listen. While learned adult AP is a poor relative to AP developed in very young children I find it extremely valuable in my work as a musician and it makes improvisation much easier. Given time this app has everything you need to begin your journey. ### 5/5 — One of a kind *2018-10-10* Definitely haven’t seen another app like this. Well thought out and very thorough. It’s early stages for me but it’s definitely already producing interesting results. ### 5/5 — Brilliant! *2018-04-11* Great app ### 5/5 — Ya’ll were not kidding! *2017-12-16* This is truly the best tool out there for developing perfect pitch. I’ve really done my research. It’s better than David Lucas Burge’s method. It’s only .99 cents too! Only thing lacking would be to extend it to develop chord progressions, melodic dictation, relative pitch training, inversions, scales etc. Some of the other main areas to developing a complete ear. I hope to see a clear pitch deluxe version or something like that one day. I would purchase in a heartbeat! Thank you so much! -Parker Nettle ## Frequently asked questions about Clear Pitch Perfect Pitch Pro ### What is Clear Pitch Pro?

The latest version of Clear Pitch Pro is 1.4.6, which was last updated on June 13, 2021. This indicates a moderate update frequency for the application. ## Version history (last 5 releases) ### 1.4.6 — 2021-06-13 Major sound update. New hybrid human-synth sounds. Users found the Yamaha voices unnatural, though in pitch & time, so we combined them with a studio vocalist recorded sound set, for the natural tone of real voice with the accuracy of synth voice. NB: vocal lyrics either human or synth are never entirely in tune re natural pitch variation but in Clear Pitch you are tuning to the instrument, with the lyrics there to assist mnemonically and for paired-associate learning, not as a reference pitch. ### 1.4.4 — 2021-05-30 Major sound update. New hybrid human-synth sounds. Users found the Yamaha voices unnatural, though in pitch & time, so we combined them with a studio vocalist recorded sound set, for the natural tone of real voice with the accuracy of synth voice. NB: vocal lyrics either human or synth are never entirely in tune re natural pitch variation but in Clear Pitch you are tuning to the instrument, with the lyrics there to assist mnemonically and for paired-associate learning, not as a reference pitch. ### 1.4.3 — 2021-05-25 Major sound update. New hybrid human-synth sound set. User advice suggested the Yamaha Vocaloid sounds were somewhat unnatural, although they were in pitch and time. The answer was to employ the best of both systems, and so using a well known studio vocalist we re-recorded the entire sound set, then combined that with the Vocaloid sounds, to create a hybrid to avail the natural nuance and tone of a real voice with the accuracy of the synth voice. Please note, vocal lyrics either from a human or a synth are never entirely in tune as there are natural variations in pitch in order to create a lifelike effect, but this is not important in Clear Pitch because you are not tuning from the vocals, you are tuning from the instrument, and the vocal lyrics exist to assist mnemonically and to facilitate paired-associate learning, so are a secondary factor when interpreting the pitch or chroma of a sound. ### 1.4.1 — 2019-07-26 Appreciation given to all Clear Pitch users who have offered development ideas.
