144.72 Hz is the frequency of Mars, derived from the planet's orbital period using the cosmic octave principle. Mars has been the warrior planet since the earliest civilisations — associated with strength, courage, determination, and the drive to act decisively.

In sound healing, Mars frequency is used to promote physical vitality, motivation, and assertiveness. It is considered a "doing" frequency — useful when procrastination, lethargy, or passivity are holding someone back. Practitioners also associate it with masculine energy and physical healing, particularly relating to the muscular and circulatory systems.

The tone has a warm, assertive quality — neither aggressive nor passive. It sits in a comfortable mid-range that many people find energising without being jarring, making it suitable for workouts, creative sessions, or any activity that benefits from sustained motivation.
