Low End: Metronome & Tuner

Low End gives you a band to practise with. Pick a key and a progression and a real grand piano plays it for you, in time with a metronome, while you play over it: scales, improvisation, your part of a song, or simply training your ear. From pop to the blues and jazz standards, with a walking double bass. A chromatic tuner completes it. Made by an amateur double bass player with the friends from the orchestra in mind, it is useful to everyone who plays. It is free, has no ads, needs no account and works fully offline. HARMONY: YOUR PIANO PLAYER • Twelve keys on a dial: touch a note and it plays on a real grand piano, recorded in stereo, in time with the metronome. • Nine progressions to play over, from the easiest, in sections for pop and rock, blues and jazz: I–VI–IV–V, I–V–VI–IV, the Andalusian cadence, the twelve-bar blues (major and minor), II–V–I (major and minor), I–VI–II–V and the circle of fifths of Autumn Leaves. One chord per bar, in phrases of 4, 8 or 12 bars, in any key, with the Roman numerals on the keys. • Example songs (Stand by Me, Sweet Home Chicago, Blue Bossa, Autumn Leaves and more) set the key, the progression, the tempo and the piano style in one tap. • Four ways to play: chords held for the bar, struck on every beat, arpeggiated, or a walking bass: a jazz line on a plucked double bass, with the piano comping lightly above it. • Or a single chord to hold (nine kinds, from major to sus4), the note alone, or a held tone instead of the piano. While it sounds, the notes not heard fade on the dial. • Start the harmony while the click is running and it comes in on the next bar, with a countdown on the dial. • Change song, progression or style while it plays: the old one fades and the new one comes in on the "one" of the next bar, as in a band. METRONOME • Tempo from 30 to 250 BPM: type it with the pencil, hold − or + to run through it, or use TAP. • Time signatures 1/1, 2/4, 3/4, 4/4, 5/4, 6/8, 7/8, 9/8 and 12/8, with the beats grouped the way you count them. • A ring that lights up beat by beat and a short, dry click that stays steady. Subdivisions in eighths, triplets, sixteenths and swing (as MuseScore plays "Swing"), or a click on 2 and 4 only. TUNER • Chromatic, with a round strobe and the note in the middle: play any note and it shows up, no string to choose first. Or pick guitar, violin, viola, cello, ukulele or bass strings. • Hears low and high notes alike, from 28 to 2800 Hz (a low B on a five-string bass up to the top of the violin and the flute). • For B♭, E♭ and F instruments it can name the written note. • Reference A: every hertz from 415 to 445 (415, 432, 440 and 442 in one tap). The sound is analysed on the phone and never recorded. • If the metronome or the harmony is playing, touch the tuner's dial and they pause, with a Resume button. MADE FOR PLAYING • Swipe left and right to change section; for rehearsals, lock the gestures in the settings. • Keeps playing with the screen off, with a notification that says what is sounding. The screen can stay on while you play. • Unplug the headphones and the sound stops, instead of carrying on from the phone's speaker. • A charcoal theme with red accents, easy on the eyes on stage; in four languages; note names as C D E or Do Re Mi. • Built to be accessible: screen-reader labels, enlargeable text, and colours that are never the only cue. PRIVATE AND OPEN • No account, no ads, no tracking, no internet connection needed. • Use the microphone to tune or record a take in Player.
