The C#4 immediately became one of the standout instruments within the BLACK KEYS series.

Compact, balanced, and incredibly satisfying in the hands, this flute carries a slightly more tactical and crafted feel while still remaining relaxed and forgiving to play.

Built through ongoing experimentation with airflow, ergonomics, and body shaping alongside our engineer Ibrahim in Egypt, the C#4 feels like a focused evolution of the C4 platform — immersive, portable, and easy to connect with right away.

The result is a tone that feels clear, expressive, and alive without becoming sharp or overwhelming.

This one feels good fast.

WHY IT HITS:

The compact proportions and balanced airflow make the C#4 feel especially fluid and natural for longer playing sessions.

Simple fingering.
No steep learning curve.

Just breath → sound → flow.

It’s beginner-friendly right out of the box,
while still offering enough richness for layering, improvisation, meditation, and ambient exploration.

440 Hz FLAVOR:

In 440 Hz, the C#4 feels slightly brighter and more present while still keeping the smooth, immersive character that makes the BLACK KEYS collection special.

Great for layering with other instruments,
group playing,
creative sessions,
and expressive melodic movement.

DISASSEMBLY / ASSEMBLY:

This drone flute arrives assembled in numbered pieces.

If disassembling:
gently wiggle each joint apart (don’t force it).

To reassemble:
follow the numbering sequence,
press pieces together partially by hand,
then gently tap into place on a soft surface if needed.

This ensures a tight seal for optimal airflow and tone.
