Odd Groupings Metronome

Odd Groupings turns a grouping into a short musical phrase, so you hear a melody that lands on the accents. Follow it with your sticking and the odd grouping starts to feel natural.

Most metronomes only click. This one builds the phrase on the accents, can hold a keys chord through the bar, and lets you mix groupings or meters when you want to. It is a practice tool made by a player, for players.

WHAT YOU PRACTICE
• Groupings of 3, 5, 6 and 7. Grouping 4 is for triplets and tuplets, where it is not just the beat.
• Subdivisions from eighths to sixteenth triplets, plus quintuplets and septuplets.
• Choose where the first accent falls inside the beat. Swing on a straight grid.
• Mixed grouping: combine 2, 3, 4, 5, 6 and 7 across the bar, with auto-fill so the bar completes.
• Accent clusters, and accent patterns such as 2+3 or 2+2+3.
• Mixed meters: 3/4, 4/4, 5/4 and 7/4, one bar or a longer form.
• Table of Time: a different subdivision per bar, per two beats, or per beat.

WHAT YOU HEAR
• A melody on the accents, in five moods (happy, melancholic, epic, aggressive, rock) and any key.
• Chord cycles: i · iv · v · i, i · VI · VII, ii · V · i, or the circle of 5ths. A short form keeps walking. A longer form stays as written.
• A keys chord through the bar, and a key walk (I, IV, V, I). V sits a fourth down. The chord cycle waits while the walk is on.
• Bass, mid and treble registers for the accents, the passing notes and the keys chord.
• Timbres: woodblock, bell, marimba, synth, tom, conga, snare.
• Metronome sounds: click, woodblock, cowbell, clave, rimshot, hi-hat.
• Separate volume for accents, passing notes, the keys chord, the metronome and the whole app. Passing-note density sets how many of the other steps sound.

HOW YOU PRACTICE
• Gap metronome: click for some bars, then none, and you keep the time.
• Call and response: hear the melody for a few bars, then play it back against the click.
• Speed trainer: raise the tempo after a few minutes or bars, up to a target, then stop.
• Sticking under the score: alternate, accent right, paradiddle, double stroke and the close variants.
• Presets saved on the device, a code you can share, and a routine that plays several presets in a row.
• Study view: score and transport only.
• Five skins: Forest, Night, Daylight, Blue, and Blue dark. The choice stays on the phone.
• Practice calendar: minutes for this week. Older days, and the best tempo of each grouping, stay on the phone too.
• Count-in of one or two bars. Stop after a set number of bars or minutes.
• The screen stays on, with an optional flash on the accents.
• Play, stop and tempo from a Bluetooth pedal or page-turner.

HOW TO USE

- Start with grouping 3 at a slow tempo. Leave the count-in on so you enter in time.
- Follow the accents with your sticking. Let the passing notes fill the space.
- Try each Start on position, to feel how the grouping sits inside the beat.
- When 3 feels natural, move to 5 and 7, then to mixed grouping.
- Use the speed trainer for a slow rise, or a routine when you want several presets in one sitting.
- Open Calendar to see the minutes. Skins are under Settings.
