Harmonium with Metronome — Tempo Practice from 40 to 240 BPM
Rhythm is half of music. Web Harmonium ships a built-in metronome that runs in the same Web Audio graph as the instrument — no extra app, no timing drift between click and note. Set a tempo, lock your scales to the click, and your hands learn to play in time rather than just in tune.
The Tempo Ladder
Indian classical music operates across four broad tempo zones. Picking the right zone for the right material is the difference between productive riyaz and frustrated practice:
Vilambit (very slow)
40 – 60 BPMRaag exploration — alap, slow bandish. Every swara has time to breathe.
Madhya (medium)
70 – 110 BPMStructured bandish, devotional kirtans, most bhajan repertoire.
Drut (fast)
120 – 160 BPMTarana, sargam patterns at speed, taan practice once the slow foundation is solid.
Ati-Drut (very fast)
170 – 240 BPMAdvanced taan and tihai flourishes. Only meaningful after slow work is clean.
Six Steps to Rhythmic Harmonium Practice
Open the harmonium
Open Web Harmonium and click Start Playing to unlock audio.
Find the metronome
Open the control panel — metronome sits next to the tanpura toggle.
Start slow
Set BPM to 60. Play Sa on each beat. Listen for the attack of the reed to land exactly on the click.
Climb the ladder
Once your scale is locked at 60 BPM, raise to 80, then 100, then 120. Only increase when the current tempo feels effortless.
Layer the tanpura
Turn on the tanpura drone alongside the metronome. Now your Sa is anchored in pitch and in time simultaneously.
Record and review
Record a 60-second pattern, play it back, and check whether your notes land on the clicks. This single habit transforms rhythm over a month.
Common Indian Taals
A taal is a rhythmic cycle with a fixed number of beats (matras). Use the metronome's beat count to subdivide each cycle and count your taal against the click.
Tintaal (16 beats)
Dha Dhin Dhin Dha | Dha Dhin Dhin Dha | Dha Tin Tin Ta | Ta Dhin Dhin Dha
The most common taal in Hindustani classical. Four 4-beat sections (vibhag). Stress falls on beats 1, 5, 9, 13.
Dadra (6 beats)
Dha Dhin Na | Dha Tin Na
Two 3-beat sections. Used widely in thumri, bhajan, and folk repertoire. Lyrical and feminine character.
Rupak (7 beats)
Tin Tin Na | Dhin Na | Dhin Na
Three sections of 3+2+2. The empty beat (khali) falls on beat 1 — unusual and gives rupak its distinctive pull.
Keherwa (8 beats)
Dha Ge Na Ti | Na Ka Dhi Na
Two 4-beat sections. Ubiquitous in folk, bhajan, and film songs. Easy entry for beginners learning to count.
Frequently Asked Questions
What BPM range does the metronome cover?
Web Harmonium's built-in metronome covers 40 to 240 BPM — the full practical range for Indian classical practice. Vilambit bandish live in the 40–60 range; drut gat and fast taan reach 180–240. Most daily practice happens between 70 and 130 BPM.
Can I practice Indian taals with this metronome?
The click is a steady beat, not a taal-specific bol pattern. Use the click as your beat reference and count the taal mentally or aloud — matra counting with the click is the standard practice method used in every gharana.
Why does my playing sound choppy at fast tempos?
Two common causes: (1) the reed attack is too abrupt — practise legato (meend) transitions at slow tempo first; (2) your finger pattern is not internalised — slow down to 80 BPM, play it 20 times cleanly, then climb back up. Rushing a fast tempo before the slow pattern is perfect creates permanent bad habits.
Is it okay to use the metronome for every session?
For structured practice yes, but also spend time without it. Once a raag is in your body, play it freely against just the tanpura — real performance has breath and pause that a metronome does not capture. Use the metronome to calibrate, then put it away.
Can I use the metronome and tanpura at the same time?
Yes. Both run in the same Web Audio graph, sample-accurately synchronised. Many practitioners turn on both for the first 15 minutes of riyaz and gradually drop the metronome as their internal pulse stabilises.
Does the metronome have an accent on the first beat?
Yes — the first beat of each cycle is pitched slightly higher so you can hear the downbeat. Adjust the beats-per-cycle setting to match the taal you are practising (4 for tintaal sub-sections, 3 for dadra, 7 for rupak).
