Doom metal practice.
Make room for the riff.

A Doom metal backing exercise with drums, bass and rhythm guitar. Repeat one idea, make space for a quiet bridge, then bring the weight back.

Your starting band

60 BPM · E natural minor · 4/4

Four editable sections from the Slow weight demo. You bring the riff; this is generated accompaniment, not a song transcription or original recording.

Open the Doom backing setup

Opening the app does not play audio or replace anything. Choose Load practice setup, then Start playback.

Before you play

  • Start at a comfortable master volume. Loading chooses Recorded Acoustic drums and rhythm guitar; synth drums play if recordings are unavailable.
  • Loading replaces the current groove, but leaves saved scene slots and master volume untouched. Save any unsaved groove first if you want to keep it.
  • The same five steps are available in Five-minute practice guide inside the app’s setup panel. The minute marks are a suggested pace, not an automatic timer. Mock Band does not advance sections or stop for you.

One riff. Five minutes. Four sections.

Use the named buttons in the practice setup panel, not the numbered Scenes slots. While playing, a section waits for the next bar. Choose once, keep counting, and listen for the change.

  1. 0–1 min

    Find the space

    Section: Slow weight

    Start with muted strums so pitch is not the task. Count 1, 2, 3, 4, then play only on beats 1 and 3. Leave beats 2 and 4 empty. At 60 BPM, each numbered beat lasts one second; one 4/4 bar lasts four seconds.

  2. 1–2 min

    Bring in your riff

    Section: Slow weight

    Try a short riff that fits the backing, or keep the same muted rhythm. Repeat it without filling every gap. Listen for whether your next attack lands with the band. There is no score and no speed target.

  3. 2–3 min

    Let the refrain breathe

    Section: Wide refrain

    Choose Wide refrain in the setup panel. Keep counting at the same pace as the drum feel opens into half-time: the BPM is still 60. Leave more space in your part instead of speeding up to fill it.

  4. 3–4 min

    Make a quiet bridge

    Section: Quiet bridge

    Choose Quiet bridge. Play fewer notes or lighter attacks against the quieter accompaniment. Keep the pulse through the spaces. This is a contrast to the heavy section, not a new tempo.

  5. 4–5 min

    Return without rushing

    Section: Heavy + toms

    Choose Heavy + toms and return to your first riff or muted rhythm. Keep it steady while the snare and tom fill arrives every four bars. Let the band supply the extra movement. Press Stop when you finish.

Make the next round yours

Choose a section first, then adjust its tempo, key or fills. Turn on Keep my tempo in the setup panel to carry your current BPM across section changes. With it off, the next section restores 60 BPM. Other edits, including key, swing and fills, are replaced by the next section’s recipe. The preference resets to off on reload.

To keep an edited groove, save it to a local scene slot you are happy to replace. Export scenes for a backup; local saves are not cloud storage.

Worth another session?

Ask yourself: did the band help you keep the riff going, or get in the way? Try the same round another day before adding more complexity.
