Virtual drums

You can play the 12 pieces directly on the panel. On a phone, touch several pads at once to combine the kick, snare, hi-hat, and claps. On a computer, the top row uses Q for the crash cymbal, W for the open hi-hat, E for the ride cymbal, and R for the agogô. The middle row uses A for the closed hi-hat, S for the high tom, D for the mid tom, and F for the floor tom. The bottom row uses Z for the kick, X for the snare, C for the rim, and V for the claps.

The layout keeps Z, X, and A close to the left hand's resting position. You can lay down a simple groove without taking your eyes off the rhythm: Z on the kick, X on the snare, and A on the closed hi-hat. The closed hi-hat cuts off the open hi-hat. Press W to open up the texture and A to close it with another hit.

At the bottom of the instrument, the sequencer lays out 16 columns. Each column represents a sixteenth note. Click a step in the row to turn the hit on or off. Start with one row at a time. Turn on only the kick and hi-hat, listen through one complete cycle, and then add the snare. The tempo can range from 40 to 220 BPM. To check the subdivision against a steady reference, also open the online metronome.

Try this one-minute exercise: select Rock, set the tempo to 80 BPM, play Z on the first and third beats, X on the second and fourth, and A on the eighth notes. Then increase it to 84 BPM. If you lose the snare, return to the previous tempo instead of speeding up by trial and error.

The kick drum carries the low-end weight and helps mark the pulse. The snare creates clear attacks on beats two and four in many rock, gospel, and country grooves. The rim has a short, dry sound. It works well for understated accents, padrões brasileiros, and patterns that need space between hits. The floor tom occupies the low register and can suggest the role of a samba-school surdo, while remaining an electronic timbre.

The closed hi-hat maintains the subdivision. The open hi-hat creates an opening at the selected point. The crash cymbal marks an entrance or a strong accent. The ride cymbal sustains a continuous layer so you do not lose the pulse. The three toms descend in register: high tom, mid tom, and floor tom. Use them in sequence to create simple fills without turning the sound into an acoustic drum recording.

The agogô adds a metallic phrase that comes through clearly in padrões brasileiros. Claps reinforce a collective accent and work well with rock, gospel, and pop strumming patterns. To compare the pulse with notes and notice how a melodic line fits over the beat, also try the virtual piano.

Quick exercise: play four bars using only Z and A. In the next four bars, add X on beats two and four. Then replace one X hit with C. You will hear the difference between an open snare sound and the drier attack of the rim.

The Samba rhythm uses two 2/4 measures at 104 BPM. The 96 to 120 BPM range is the reference Cantivy uses for this pattern. The kick drum takes the role of the surdo: it appears on the first beat, receives a lighter note on the last quarter of the beat, and creates an accent on the second. The surdo de primeira reinforces the second beat and creates a low response.

The hi-hat appears on all four sixteenth notes of each beat. The last sixteenth note receives an accent. This repetition helps you hear the subdivision even when the kick drum plays fewer notes. If the grid seems crowded, reduce the tempo to 60 or 72 BPM. Count four positions within each beat: 1, 2, 3, 4. Increase the tempo only after repeating the pattern without anticipating the second beat.

The agogô follows the two-measure phrase of the 3:2 pattern: LL.L.H.H|L.L.L.H. In the original notation, L is the low agogô bell and H is the high one, and the dot indicates a rest; here, both bells become a single line on the grid. First, listen only to the agogô. Then turn on the hi-hat and, lastly, the kick drum. This order makes it easier to identify which layer is ahead of or behind the beat.

Two-minute practice: keep your left hand on Z and A, play the kick drum on the grid positions, and add the agogô on the R key. Do four cycles at 72 BPM. Then increase to 80 BPM and compare the stability of the subdivision. To study references for the style, read the material about samba without trying to copy a specific recording.

The Baião rhythm uses two 2/4 measures at 120 BPM. The 110 to 140 BPM range is the reference Cantivy uses for this rhythm. The kick drum represents the zabumba figure with a dotted eighth note followed by a sixteenth note. On each measure's grid, this cell appears on steps 1 and 4. Listen to the low part by itself before adding any other piece.

The rim enters on the second beat. The hi-hat fills the sixteenth notes in place of the triângulo and receives an accent on every beat. The kick drum concentrates the low cell, while the rim and hi-hat make the two-beat cycle easier to follow. First, play only Z. Then keep Z and add C on the second beat. Finally, turn on A for every sixteenth note.

This combination is useful for studying a forró strumming pattern without presenting a recording of zabumba, triângulo or pandeiro. The tone remains electronic and synthesized. Compare 110, 120 and 140 BPM. If the cell loses its shape when you speed up, return to the previous tempo and remove the hi-hat for three cycles. Then reintroduce A without changing the kick drum.

To check the tempo of your own idea, use the BPM counter. Clap for 15 seconds, check the estimate, and then try to reproduce the same pulse on the grid.

The Bossa nova rhythm uses two 2/4 measures at 130 BPM. The 120 to 140 BPM range is Cantivy's reference for this pattern. The kick repeats a low-volume surdo figure and works as a low shadow. The rim and the steady hi-hat stay at the front of the mix. If the low end draws more attention than the rim, turn off the kick for four cycles and turn it on again.

The hi-hat plays eighth notes. The rim plays the Brazilian clave X..X..X...X..X.., described here as a 3-2 son clave with the last hit delayed by a sixteenth note. Each symbol occupies one position on the grid. X indicates a hit. A dot indicates a rest. Read the 16 positions slowly and tap only the Xs with your finger before playing the entire pattern.

Start with the rim and hi-hat, leaving the kick off. Then add the low kick and play over it without speeding up. The relationship between the rim's dry attack and the eighth notes must remain clear. If you lose your place, count “1 and 2 and” in each measure and keep your body moving with the pulse, without accenting all 16 steps.

Play four cycles at 80 BPM, four at 100 BPM, and four at 120 BPM. Return to 130 BPM only if the rim stays in place. To expand your listening, see the bossa nova content and, to play along more slowly with a bossa nova recording you already have, open the Cantivy Studio.

The Rock rhythm uses a 4/4 time signature at 110 BPM. The kick plays on beats one and three, as well as on the offbeat after beat three. The snare enters on beats two and four. The hi-hat plays eighth notes. This foundation makes the relationship between the pulse, the offbeat, and the backbeat clear. It also serves as a starting point for country, worship music, and pop.

Read the grid this way: each row corresponds to a piece, and each column corresponds to a sixteenth note. A larger circle represents an accent. An outline indicates a ghost note. Regular dots mark standard hits. Turn on one column at a time and count “1 and 2 and 3 and 4 and,” keeping four subdivisions within each number. This count separates beat three from the offbeat that follows it.

After you understand Rock, turn off one piece and replace one hit with another. Swap the snare for the rim to create a drier accent. Replace one closed hi-hat hit with an open hi-hat hit to test an opening. Change the tempo between 40 and 220 BPM, but prefer increases of 4 BPM. Four cycles at 80, 84, 88, and 92 BPM are more useful for studying control than jumping directly to 120 BPM.

The pattern is saved only in this browser. It is not a recording and does not become an exported audio file. To record a performance, use the in-browser audio recorder, which is separate from the virtual drum kit. Make a 20-second recording and check whether the pulse remains steady from beginning to end.

When you play a piece, the browser triggers the sound the moment you touch it. The sounds are synthesized with oscillators, noise, filters, and envelopes. They are not played back from recordings of an acoustic drum kit. This process preserves the electronic drum character of the kick drum, snare, cymbals, agogô, claps, and the other kit pieces.

You may notice a delay in the path between the device and the headphones. Bluetooth headphones often add latency. Some Android phones also have more noticeable delay, depending on the model, browser, and device workload. Does the tool depend on the microphone? No. The drum responds to your touch, but the audio output still depends on the equipment playing the sound. Try wired headphones or the phone's built-in speaker before practicing a fast subdivision.

Try this simple test: play the snare on beats two and four while tapping your foot at 60 BPM. If the sound seems out of sync with the movement, repeat the test with wired headphones and then with the speaker. Compare all three results. Close demanding tabs, keep the page open, and practice on the same equipment you plan to use for studying.

The sequencer repeats the pattern without depending on your reaction time, but touch response and audio response may vary by device. To organize your practice, combine the drum pattern with the online metronome and review fundamentals in music theory for beginners.

• Use Z, X, and A for the kick, snare, and closed hi-hat with your left hand near its resting position.
• Read each column as a sixteenth note. Larger circles indicate accents. Outlines indicate ghost notes.
• Start with the Samba, Baião, Bossa nova, and Rock presets before building your own grid.
• Lower the tempo to 60 or 72 BPM when you need to identify each subdivision.
• Increase it in 4 BPM steps and repeat four cycles before increasing it again.
• Use wired headphones or your device's speaker when Bluetooth or a particular phone delays the sound.
• The programmed rhythm is saved only in this browser. The tool does not create an exported audio file.

Cantivy's virtual drum kit is designed to help you hear the subdivision, test your coordination, and repeat small changes. The sound remains electronic. The four presets show different ways to distribute low-end hits, timekeeping, subdivisions, and accents. You can start with a ready-made grid and change just one piece at a time.

If you want to combine the beat with other tools, open the Cantivy Studio to work with a file you already have. To record a performance, use the separate recorder. The virtual drum kit remains the place to play, program, and study rhythms directly in your browser.
