Guitar fingerboard

1. A stringed instrument comprising:

A body;

an elongate neck;

a headstock;

wherein the neck includes a fingerboard, the fingerboard having fixed, spaced-apart frets disposed perpendicularly along its length and extending from a first to a second side of the fingerboard, a top surface of the frets forming a fret plane, the fret plane having a first and second convex radiused surfaces, the first surface extending from an upper edge of the plane towards a center thereof and the second surface extending from a lower edge of the plane to a center thereof; and

wherein the first surface forms a smaller radius and the second surface forms a larger radius.

2. The stringed instrument of claim 1 , wherein the surface of the fingerboard has corresponding first and second surfaces.

3. The stringed instrument of claim 2 , wherein the instrument includes a plurality of strings arranged side-by-side along the length of the fingerboard and forming a string plane, the string plane including corresponding first and second surfaces.

4. The stringed instrument of claim 3 , wherein the strings are constructed and arranged to be depressed between frets.

5. The stringed instrument of claim 4 , wherein the strings are suspended at a first end by a nut and at a second end by a saddle, the strings in their unfretted position increasing in height between the nut and the saddle.

6. The stringed instrument of claim 5 , wherein the instrument includes 6 strings and at least the smallest diameter string is displaceable towards a centerline of the fretboard.

7. The stringed instrument of claim 6 , wherein the instrument is a guitar.

8. The stringed instrument of claim 7 , wherein the instrument is an acoustic guitar.

9. The stringed instrument of claim 8 , wherein a top of the guitar acts as an acoustic soundboard.

10. The stringed instrument of claim 7 , wherein the instrument is an electric guitar.

11. The stringed instrument of claim 1 , wherein the first smaller convex radius is a radius measuring about 10 inches and the second larger convex radius is a radius measuring about 15 inches.

12. A guitar, comprising:

an elongate fingerboard;

a plurality of frets, each disposed perpendicularly along the fingerboard;

three larger diameter and three smaller diameter spaced-apart strings running the length of the fingerboard, the strings suspended by a nut at a first end and at a first height and suspended by a saddle at a second end and at a second greater height; and

an upper surface of the frets forming a fret plane along the length of the fingerboard, the fret plane divided into a first smaller convex radius under the larger strings and a second larger convex radius under the smaller strings, whereby a smaller string, when displaced towards a centerline of the fingerboard will have a smaller rise/run ratio than a larger string displaced towards the centerline.

13. The guitar of claim 12 , wherein the size of the first smaller convex radius is about ⅔rds the size of the second larger convex radius.

14. The guitar or claim 12 , wherein the first smaller convex radius is a radius measuring about 10 inches and the second larger convex radius is a radius measuring about 15 inches.
