Sound bar for a musical instrument and method of making thereof

A method of making and tuning a sound bar to multiple target frequencies, comprising:

• (a) measuring the frequency of an uncut sound bar;
• (b) determining a first and a second target frequency;
• (c) calculating a first and a second notch size based on the first and second target frequency;
• (d) cutting into the bar on the first face to the calculated first size, and on the second face to the calculated second size;
• (e) measuring the first and second new frequencies of the cut bar;
• and
• (f) iteratively repeating the steps (a)-(e) based on the measured new frequencies until the multiple target frequencies are reached.

A musical instrument comprising:

• one or more sound bars, each sound bar comprising:
• a prismatic bar having four faces, a first end and a second end;
• a first notch on a first face of the bar;
• and
• a second notch on a second face of the bar;
• wherein the first face is orthogonal to the second face;
• and
• a first base rod and a second base rod positioned parallel to each other;
• wherein the one or more sound bars are positioned perpendicular to the base rods, and each sound bar is attached at a first position to the first base rod, and at a second position to the second base rod.
