Supercharge Your Rhythmic Vocabulary
Supercharge Your Rhythmic Vocabulary with Metric Flow!
Practice improvising and become inspired with an endless supply of rhythms whilst working on your phrasing and rhythmic control.
Generate Endless Rhythms with Ease
Metric Flow automatically creates one-bar rhythmic patterns (based on 16th note subdivisions) in your chosen time signature, providing a versatile improvisation practice tool for developing your rhythmic vocabulary and control. The app supports all common, odd, and complex time signatures, including polyrhythmic overlays such as 7/8 or 5/16 over 4/4, helping you master phrasing across barlines and expand your modern rhythmic vocabulary. Simply tap the ‘Generate Rhythm’ button for a new pattern, then press ‘Play’ to listen at your selected tempo. Adjust the speed using the tempo slider or tap tempo feature, ranging from 40 to 200 BPM.
Rhythmic Customization Options
Metric Flow offers sophisticated customization features that allow you to refine the randomly generated rhythms. You can add rests, dotted rhythms, 16th notes, and vary levels of syncopation. These options provide greater control and flexibility, enabling you to tailor rhythms to suit your practice and compositional needs.
Visual Rhythm Representation
The intuitive ‘Timeline View’ employs animated dots to visually depict your rhythms based on 16th note subdivisions. This visual approach eliminates the need for reading traditional notation; downbeats are clearly marked for each time signature and update in real time, even with complex polyrhythms extending over bar lines. This makes understanding note and rest durations straightforward and accessible, fostering ear training and internalization of rhythmic patterns without prior music theory knowledge.
Creative Rhythm Variations & Audio Export
You can tap directly on the rhythm visualization to cycle the rhythm elements around through the bar, giving you many variations of a single loop. Alternatively, tap the arrow icon above the rhythm to shift the whole rhythm forwards by one 16th note, exploring every permutation of that rhythm throughout the bar and create phrases that cross over the barline. Once you find a rhythm you like, tap the heart icon to save it to your favorites, or export a single, perfect cycle as a WAV or AAC file. These exported loops can be shared or stored on your device, complete with tempo information for seamless synchronization in your DAW with backing tracks, drum patterns or even in your compositions. You could even combine multiple, single exported loops in different time signatures to create complex rhythms that cross over the barline and expand your creativity in any genre.
Enhanced Practice Features
Metric Flow enhances your practice sessions with a built-in drone synthesizer pad for harmonic support and an optional 16th note swing to add groove and feel to your rhythms. Save your favourite rhythms to practice with later or use them as inspiration for writing melodies, riffs and songs. These features help develop your timing, feel, and musicality in an engaging and effective manner.
