Overview Learn a very straight forward approach as how to play over minor II V's. You will no longer have to fear a half diminished chord followed by an altered dominant! This app will give you the tools to play these types of chords so that you sound well beyond your current years of improvisational experience. Beginners and advanced players can benefit from focusing on specific keys and progressions for Jam-A-Long. Each Jam-A-Long allows the user to select any key to improvise in over an endless loop. Tempos are also adjustable. The Minor II V is one of the more common, yet often ‘fluffed’ over, progressions found in the jazz repertoire. Our goal is to take the mystery out playing over these progressions. The Jam-A-Long includes focus on individual chords as well as in a progression. We have also defined the scale to chord relationships for each key and allow the user to listen to the isolated scale as well as hear it over the appropriate chord. We also offer a method to best practice these scales and progressions. Features- Full explanation of the concepts involved. Detailed Theory of note to chord relations. Audio and visual representation of the scales. Audio playback of the scales played over the appropriate chords. Jam-A-Long for each isolated chord in all keys. Jam-A-Long for each progression in all keys. Each Jam-A-Long was recorded individually as to give variation for each key. Mixer control for the Jam-a-Long instruments. Tempo Control for each Jam-A-Long. ## Key features - Minor II V progression explanation - Note to chord theory - Audio/visual scale representation - Scales over chords playback - Key-specific Jam-A-Longs - Adjustable tempo and mixer ## Recent user reviews (8 of 8) All indexed reviews: https://appshunter.io/ios/app/iimprov-the-minor-ii-v/id421582805/reviews.md ### 4/5 — Very good *2014-11-04* I love the way you can transition from theory, to practice and hear the chords and scales played on real instruments as examples while you learn. A good addition to the App Store. ### 5/5 — Excellent work dev, kudos to you!! *2013-06-25* Bravo! Extremely well done! Thank you so very much for caring enough and taking the time to do this fine explanation. And thank you again for the great tools you've created in the jam along loops. Bravo!! ### 5/5 — These iImprov apps beats out college *2011-09-22* This app and the sister "modal" app, are the ultimate jazz woodshedding and jazz theory/practice tools - forget Aebersold. If only there'd been something like this when I was at college, I could have stayed home, practiced with these apps, and saved myself the tuition fees! Useful interface, simple and comprehensible explanations, and the backing tracks, tho' apparently sequenced, do actually manage to swing/groove. Perhaps a few areas for improvement: 1) option to add the I-chord to follow after the ii7b5-V7alt in the backing track sequences, and 2) the facility to alter the duration each chord is held for in a ii-V7-i/I sequence, 3) the ability to run the app in the background (multitasking), 4) add a recorder/notation sketch page so ideas can be captured. And oh yes, hurry-up please!!!! with the other apps promised in the series. :-)) ### 1/5 — scales *2011-08-31* would've been better to have audio examples of licks and phrases derived from the scales that one can use to play over the ii-v pattern. ### 5/5 — Really helpful *2011-08-13* I play both trumpet and piano, and this app really helps to focus in on the minor II and V, just like it says it does. Very simple and straight forward. Good work! ### 5/5 — Iimprov app *2011-08-06* Excellent clearly written explanation of this common progression in jazz, including notes to use when improvising over the progression, and it has a practice tool in all keys. As a beginner/intermediate student, this app is very helpful. ### 5/5 — Great way to practice *2011-04-14* great app for jazz practice and jazz teachers with many interactive tools to use. The app does a great job of showing you the info and letting you explore it. Explanations are simple and easy to understand! Keep em comin'!!! ### 4/5 — Good tool to learn jazz detail *2011-03-27* This is for just practicing minor 2-5 chord sequences. With that focus, I find it helps me keep working at this important jazz concept, rather than letting me escape to something new too quickly. As a piano player I would have liked the authors to add suggested left hand piano voicings. I would also like to see some example solo lines. But the app delivers what it says it does. I will look for more from this company. ## Frequently asked questions about iImprov ### What is the main focus of iImprov? iImprov focuses on teaching and practicing the minor II V progression, a common element in jazz repertoire.
