## Abstract

Improvements in acoustical and stringed musical instruments (e.g., guitars) are disclosed.

## Claims

### Claim 1

A musical instrument comprising:
a body that defines a resonance chamber and that features a soundboard with a sound hole; and,
a bridge that is affixed to the soundboard, the soundboard configured so that the affixed bridge is mechanically connected to a string that extends through the sound hole with at least a portion of the string being located within the resonance chamber,
wherein the bridge is affixed to an underside of the soundboard inside the resonance chamber.

### Claim 2 (depends on 1)

The musical instrument of claim 1 wherein said configuration of the soundboard is a surface thereof that is oblique relative to another surface thereof and that is positioned adjacent to an opening in the resonance chamber.

### Claim 3 (depends on 2)

The musical instrument of claim 2 wherein said oblique surface is a bulge in the soundboard.

### Claim 4 (depends on 2)

The musical instrument of claim 2 wherein the bridge is affixed to oblique surface of the soundboard.

### Claim 5 (depends on 1)

The musical instrument of claim 1 further comprising: a neck with a plane; and, wherein said configuration of the resonance plate is a surface thereof that is oblique to the plane of the neck and an opening in the soundboard.

### Claim 6 (depends on 5)

The musical instrument of claim 5 wherein the bridge is affixed to the oblique surface of the soundboard.

### Claim 7

A method of installing a string on a musical instrument with a resonant chamber that features a soundboard with a sound hole, the method comprising the steps of:
affixing a first end of the string to the musical instrument at a first location that is not within the resonant chamber;
affixing a second end of the string to the musical instrument at a second location so that at least a portion of the string suspends through the sound hole to within the resonant chamber; and
affixing a bridge to the soundboard, the soundboard configured so that the bridge is mechanically connected to said string,
wherein the bridge is affixed to an underside of the soundboard inside the resonance chamber.

### Claim 8 (depends on 7)

The method of claim 7 wherein said second location is on the soundboard.

### Claim 9 (depends on 8)

The method of claim 8 wherein:
the musical instrument features a neck that extends from said resonant chamber to a headstock; and,
the first location is on the headstock.

### Claim 10 (depends on 9)

The method of claim 9 wherein the neck is oblique relative to the resonant plate.

### Claim 11 (depends on 8)

The method of claim 8 wherein:
the soundboard features a surface thereof that is oblique relative to another surface thereof and that is positioned adjacent to an opening in the resonance chamber; and,
the second location is on the underside oblique surface.

### Claim 12 (depends on 11)

The method of claim 11 further comprising the step of threading the string through the opening in the resonance chamber.

### Claim 13 (depends on 11)

The method of claim 11 wherein the oblique surface is a bulge.
