The Living Harmonic Wheel

Touch a planet to illuminate and hear its exact AHS pitch, or begin a musical journey around the wheel.

✧ Geometric Frequency Atlas · match patterns to planetary notes

Experimental mathematical pitch mappings, not natural frequencies measured from these shapes. Each pattern is referenced to the natal ASC Home; matches are compared in cents.

✧ Minor bodies and lunar nodes

Chiron and the True North/South Nodes are included when available from the ephemeris. Choose whether they appear in the wheel and performance voice mixer. Optional asteroids are calculated only when accurate ephemeris data is available; unavailable bodies are reported, never estimated.

Choose an instrument and press Test, or touch a planet. Recorded samples have distinct timbres.
♫ Live AHS Ensemble

Choose several instruments to play the same chart-derived notes together. The sustained Home layer follows your Ascendant frequency.

Live ensemble is separate from the exported WAV arrangement.
🥁 Live backing rhythm & genre

Play a beat behind your chart-derived instruments. Beats are generated percussion (not studio drum recordings); natal frequencies stay unchanged.

Choose a genre, then start the beat. Backing is for live listening; WAV export uses the separate Performance Studio arrangement engine.

Chart layers · compare moments and people

Overlay another chart

Calculated layers share the same natal orientation. Add multiple charts for visual comparison.

Calculate a comparison chart here, then switch its display on or off.

☼ Planetary / Solar Journey

Calculate exact annual solar returns from your natal Sun longitude. Natal AHS Home and natal frequencies remain fixed. Every return is a dated overlay, not a replacement natal chart.

48 years × 15 seconds = 720 seconds (12 minutes) of sounding music; plus 10 seconds silence at each end.
No additional layers yet.
For Solar Returns, calculate the exact solar-return instant first. This comparison tool currently accepts a specified date and time; it does not find solar-return instants automatically. Historical UTC offsets must be checked.

✧ QUICK CHART ACTIONS

One form · two destinations

Enter another person's birth details above, then choose where to send their chart. Send to Overlay preserves your original wheel. Send to Wheel calculates a new main chart.

Calculate your first chart, then add another person's chart as an overlay.
1. Calculate your first person once. Their planets stay on the main wheel. 2. Add other people using “Add overlay” in your saved library or the five spaces below. Their planets appear as comparison layers without replacing the first person.
✧ CALCULATED CHART COMPARISONS

My Five Overlay Spaces

Save five events, people, transit moments or solar-return dates here. Calculate any selected spaces or send all five calculated overlays to the Celestial Wheel together. These are separate from your five saved natal profiles.

Fill in dates, times and coordinates. Check each location's historical UTC offset.

✧ Christmas 2026 · AHS event chart

Load a festive Manchester sky chart for 25 December 2026 at 3:00 pm GMT. This is an event chart, not a natal birth chart. You can change the date, time or location afterwards.

Chiron is always calculated when its ephemeris data is available. After calculating, check Technical details & warnings for any missing body.

Example values are placeholders, not your personal birth chart. Please check the date, location and historical time offset before calculating. For 2 April 1978 in Northampton, use UTC offset +1 (BST); 22:35 local = 21:35 UTC.

The Harmonic Breath

A journey from silence, through expansion, to Home

SilenceEmergenceCrescendoReflectionHome
Expressive dynamics only · the AHS pitch mapping remains fixed.
✧ v3.1 · Planetary performance layers

Choose an accompaniment, including Gentle pulse for rhythmic beats. Use the wheel’s “Sound aspect chords” or “Aspect relationship journey” to perform the calculated relationships. The expanded Iowa sample library includes woodwinds, brass, strings and percussion. New recordings are playable on the main wheel and its live ensemble. The Performance Studio WAV renderer does not yet render all new samples; its instrument palette is a creative selection, not a guarantee of recorded-sample export.

🎵 Backing music and beats — choose below

Pick the accompaniment and instrument, then press ♫ Create this arrangement at the bottom of this page. Open Listen & Export to hear the newly generated recording. Selecting a backing alone does not immediately change the existing audio.

Planetary voice mixer

Choose which bodies sound in the journey and in arrangements after pressing Create this arrangement. Use All, None or Solo. Your chart still shows every calculated position.

Performance palette

The style selection describes the interpretation; choose an instrument palette and press Create this arrangement to apply the supported sounds.

Only available for Harmonic Breath Meditation. Turn off to export without silence. Other styles never add this padding.

Performance controls change tempo and timbre only. The calculated AHS frequencies and ASC-relative geometry remain fixed. WAV adds optional 10-second opening and closing silence only for Harmonic Breath Meditation. Verified Iowa sample modes use note recordings from the University of Iowa Musical Instrument Samples collection, pitch-shifted to the exact AHS frequency. The wheel now offers real Iowa guitar and Thai gong recordings as well as synthesized alternatives.

From planetary angles to musical intervals

In AHS, a full 360° circle maps to 1,200 cents (one octave). That makes a 60° sextile 200 cents (two semitones), a 90° square 300 cents (three semitones), a 120° trine 400 cents (four semitones), and a 180° opposition 600 cents (six semitones), when measured as the shortest separation. These are intervals, not automatic major or minor chords.

A chord needs at least three notes. The AHS hybrid progression combines actual chart pitches, with houses influencing rhythm. These musical descriptions are interpretations, not physical evidence of planetary sound.

Hybrid AI arrangement · preparation mode

Generate the deterministic AHS WAV/MIDI here, then use the exported MIDI and musical instructions with a separately connected AI music service. This edition does not claim to generate AI audio itself.

Available now · AHS-to-AI Music Generator
AI Music Prompt Generator

Create an instrumental AI music prompt from your calculated AHS chart, including planetary notes, instrument voices, aspects, house rhythm and Home tonic. The prompt stays under 1,000 characters and can be copied into a compatible AI music generator. Exact note compliance depends on the external service.

✧ Shape your AHS musical journey

Choose arrangement, feeling, development and sound texture independently of the performance style above.

✧ Natal + transit orchestral prompt

First calculate your natal chart, then add a dated transit layer in the Wheel tab. The prompt uses the calculated natal notes and the selected overlay, rather than guessing planetary positions.

Aspect motifs are based on the current chart; an external AI generator may reinterpret exact notes or silence.
