Automated player for stringed instruments

An automated player for playing an unmodified stringed instrument comprising:

• (A) at least one plucking mechanism operable to selectively and releaseably contact and displace a corresponding instrument string such that the instrument string vibrates and produces a sound, and wherein said plucking mechanism further comprises
• (i) a string-contacting portion rotationally mounted relative to the corresponding string and having a rotational axis substantially parallel to the corresponding instrument string, said string-contacting portion including at least one extendable quill,
• (ii) a first drive member in mechanical communication with said string-contacting portion and capable of creating relative movement between the first drive member and the string-contacting portion,
• (iii) an actuator in mechanical communication with said at least one extendable quill, said actuator operably engaging at least one quill such that there is relative movement between the actuator and the quill, whereby said at least one quill is selectively extendable to vary the displacement of said string during a rotation of said string-contacting portion;
• and,
• (B) at least one fretting mechanism operable to selectively depress the corresponding instrument string such that the vibration of the instrument string occurs over a desired string length, said fretting mechanism comprising:
• (i) a carriage operable to be placed in depressive contact with the instrument string;
• and,
• (ii) a second drive member in mechanical communication with the carriage and capable of creating relative movement between the second drive member and the carriage, said second drive member operable to selectively position the carriage.

An automated player for playing an unmodified stringed instrument comprising:

• (A) at least one plucking mechanism operable to selectively and releaseably contact and displace a corresponding instrument string such that the instrument string vibrates and produces a sound, and wherein said plucking mechanism further comprises
• (i) a string-contacting portion rotationally mounted relative to the corresponding string and having a rotational axis substantially parallel to the longitudinal axis of the corresponding instrument string, said string-contacting portion comprising four spokes extending radially with respect to a central bore, each of said spokes including a quill slot adapted for receiving an extendable quill, said spokes further including a first edge having a substantially rounded periphery, whereby said first edge is operable to be selectively brought into contact with said string to variably damp string vibrations,
• (ii) a first drive member in mechanical communication with said string-contacting portion and capable of creating relative movement between the first drive member and the string-contacting portion, said first drive member comprising a first stepper motor,
• (iii) an actuator in mechanical communication with said extendable quills, said actuator operably engaging said quills such that there is relative movement between the actuator and the quills, said actuator including a shaft coupled to a solenoid, said shaft having a tapered end adapted to engage said extendable quills, whereby said solenoid is energized to selectively extend said quills to vary displacement of said string during a rotation of said string-contacting portion;
• and,
• (B) at least one fretting mechanism operable to selectively depress the corresponding instrument string such that the vibration of the instrument string occurs over a desired string length, said fretting mechanism comprising:
• (i) a carriage comprising a segment of tubing mounted to a flexible belt and adapted to be placed in depressive contact with the instrument string;
• and,
• (ii) a second drive member in mechanical communication with the flexible belt and capable of creating relative movement between the second drive member and the carriage, said second drive member comprising a second stepper motor operable to selectively position the carriage.

A method for electronically playing a musical instrument having a plurality of strings and a plurality of frets extending transverse to the strings, said method comprising:

• a) selectively rotating at least one of a plurality of first members, each first member being associated with one of the plurality of strings of said musical instrument and each adapted to rotate about a rotational axis substantially parallel to the associated string, each first member having an electrically operated driver which when energized rotates the associated first member, each first member having a string contacting member extending radially outwardly from the rotational axis of said first member a sufficient distance to contact and effect plucking of the associated string when said first member is rotated;
• b) selectively moving at least one of a plurality of string depressing second members substantially parallel to the string, each of said string depressing members being associated with one of the plurality of strings of said musical instrument and each second member having an electrically operated second driver adapted to move the associated second member to a position above one of the frets of the musical instrument and adapted to press the associated string into contact with said one fret in time with the rotation of the first member associated with that string;
• and,
• c) electronically energizing said first and second drivers to effect plucking and fretting of the strings of said musical instrument in a predetermined time sequence to effect playing of the instrument.
