## Description

The just-intonation tuner with a live lattice. See ratios, cent deviation, and explore 3-31 limit ratios in an interactive lattice. Built for performers & composers.

Tenney is a musician’s tuner with a live interval lattice. It helps you hear and see how any note relates to a chosen root pitch using simple fractions (like 3/2), with tools that help you practice in just intonation.

Hear intervals, not just notes

* Live pitch readout with ratio, ± cents vs 12-TET, and Hertz
* Confidence meter to judge how stable the pitch is
* Adjustable root (e.g. 415, 440 Hz) and prime-limit controls
* High-precision pitch tracking designed for real-world performance conditions

Explore a live lattice

* Interactive 3×5 interval plane with smooth pinch-to-zoom and panning
* Tap any node to see its ratio, cents, and Hz at a glance
* Prime overlay chips (7, 11, 13, and beyond) reveal higher-prime families
* Axis Shift ribbon (±3/5/7/11) to slide the lattice along musical directions
* Selection tray to collect intervals while you explore

Made for the way JI musicians think

* Ratio-centric labels with proper oddization and factoring
* Prime-limit control (3/5/7/11/13+) to match your harmonic language
* Detection “strictness” options (Loose / Performance / Strict) for different contexts
* Designed to feel immediate, informative, and stage-safe

Thoughtful by default

* Works offline; no accounts, no ads, no tracking
* Light and Dark appearance support, portrait and landscape with beautiful themes
* Fast, fluid UI that takes advantage of Apple’s latest glass effects where available
* Built to sit comfortably beside your other pro music tools

What’s in this version

* New tuner modes with ratio labels, cents vs 12-TET, and confidence
* Expanded lattice: explore intervals, toggle prime overlays, shift axes, build selections, make scales you can play in-app

Who it’s for

* Performers and composers working in just intonation
* Ear-training, rehearsal, and structural exploration of JI spaces
* Anyone curious about harmonic relationships beyond 12-TET
