HelloMusic – Metronome & Tuner

HelloMusic is a practice toolbox for musicians. A friendly white cat keeps you company while you work on timing, tuning and learning songs.

METRONOME
• 20–300 BPM. Turn the dial or double-tap to type a tempo

• Advanced rhythms (Pro): quintuplets, sextuplets, cross-rhythms, son clave
• Tap a beat to change its accent, or put accents on 2 and 4 in one tap. Separate click and subdivision volumes
• Count-in: a voice counts one or two bars before you start
• Tap tempo to find the speed of any song
• Practice timer: stops at the end of the bar when time is up

SONGS (SETLISTS FOR DRUMMERS)
• Lay out songs by section — intro, verse, chorus — each with its own bars, tempo, time signature and rhythm
• An odd bar with an extra beat? Change the beats of that one bar. Pickups count in correctly
• Free-time passage? Stop after a section and tap Continue to go on
• Big section and bar display, with early warnings before changes
• Chain up to 3 songs seamlessly; share songs with your band

TUNER
• Live note, cents and frequency

• Quick guitar string select, or auto-detect

• Chord analysis: detect the chords of a whole song, then transpose, simplify and turn them into a setlist song
• Vocals view: lyrics, chords and bars on one screen, and the screen stays awake while playing

RECORDING
