Chord! is a chord and scale reference that works with any fretted instrument like guitar, basses, ukulele, banjos,… It computes and analyses all the possible fingerings for chords, scales, and arpeggios. With Chord!, you can also write a song by simply dragging and dropping chords, transpose it in any key, compute the fingerings with any tuning and generate a beautiful print-ready PDF, etc. You can also import your existing songs in text format (please note that the app does not ship with songs). You can also link audio tracks from your music library and play them at the same time while adjusting their pitch and/or speed. You don't even have to know music theory to use it: behind its brute force, the app knows how to handle by itself some subtleties of music to give meaningful results. If you don't have to be an advanced player to use the app, you can however take a look under the hood and tweak the parameters if you like! Whatever is your level or your instrument, Chord! will adapt and give you the most precise answer. You can search for any chord, split (like D/F#), or not. If you're a beginner, you can choose the chord from a list, but you can also use the intelligent keyboard to enter the chord as it is written. If this keyboard is a great way to enter chords, it is also very useful to discover and understand how the chords are formed. You can also enter some notes on a neck to find which chords it can be. You can hear how each fingering sounds. Chord arpeggios are also supported, as well as drop voicings (drop 2, drop3, etc.). The app also ships with the biggest list of named scales (and you can create your own scales). It analyses and presents them with nice interactive views (scale, score, and keyboard). Of course, it can also lay down these scales on a neck (with sound) and compute their fingerings. Like for chords, you can even search for a scale from its fingering! Each scale can be harmonized (decomposed into chords). You can also enter a sequence of chords to find which scale you can use to improvise onto. You can use one of the hundred tunings that ship with the app, or you can add your own ones, for any instrument, with or without a capo, even with broken strings if you want! The app uses custom and unique algorithms to generate charts, easily input complex harmonic structures, extract chords from fingerings, determine finger positions, compute keys of scales, generate chords from scales and find scales that go well with some chords. For example, Chord! is the right tool in these situations: • You want to have your songbook available at any time, in your pocket; • You're a beginner and you want to know how to play easily a D/F# chord; • One gave you a ukulele and you want to know how to tune it and how to play the G Hawaiian scale; • You want to know on what scale you can improvise for some chord sequence (and the answer can be different than the Pentatonic minor!); • You want to print your song and share it with your band. • You want to experiment with this nice open tuning, moreover with a bottleneck; • Your little sister can't make bar chords and you want to show her how she can do without bars, with three (little) fingers only; • You want to impress your little sister by showing her how you can play the same chords with two bars! • You want to understand how this fingering for C13 is actually a fingering for C13; • You broke a string and want to know how to play some chords without; • You want to know how Django managed to play with two and a half fingers. The app fully supports left-handed instruments. Main functions of the app: - Write, transpose, fingerize, print, and share songs; - Search chord fingerings (or chord charts); - Search chords from fingerings; - Search scale fingerings; - Search scales from fingerings; - Search chords from scale; - Search scales from chords.
