## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/402,711, filed Aug. 13, 2002.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to metronomes, and more specifically to a programmable metronome which is useful for conducting beginning music students and further useful as a practice device and/or a teaching aid for reminding beginning music students of the correct beat, tempo and measure to play in a song selection from a sheet of music.
2. Description of Related Art
A major problem associated with coordinating musicians is having the participants play a piece of music together on the same beat and measure, particularly musicians that have not acquired the ability to read music. It is not uncommon for beginning music students to lose their timing for the playing of notes and also their places on the music sheet. Measures are frequently ‘counted out’ by the instructor/conductor during practice in order for the student/musician to ascertain the place on the sheet of music where the instructor/conductor desires for playing to begin. However, this practice is generally considered as unacceptable when it takes place during a performance.
The use of electronic audio and video displays to assist in conducting live musicians is well known in the prior art. For example, U.S. Pat. No. 5,275,082 issued Jan. 4, 1994 to Kestner-Clifton et al. shows an electronic visual music conducting device adapted to receive electronic timing signals representative of the tempo of a piece of music and to use the timing signals to control a visual display indicates tempo and rhythm by simulating the movement of a conductor's baton. The device can include a bar display to indicate numerically which bar is currently being played and a beat display to indicate numerically the number of beats per minute associated with the bar currently being played.
U.S. Pat. No. 5,214,228 issued May 25, 1993 to Hoiles et al. teaches an electronic metronome having a selector switch, three visual indicators, and a programmable counter coupled to the selector switch and the visual indicators for providing various sequential time signature displays. A speaker is used for providing an audible beat pattern for the student/musician. The metronome of Hoiles et al. provides (1) a digital readout on a three digit, seven-segment light emitting diode display of the number of beats per minute, (2) an audible tick-tock rhythm, and (3) various visual patterns on an array of three distinctly colored light emitting diodes corresponding to available beats per measure time signatures.
U.S. Pat. No. 5,447,089 issued Sep. 5, 1995 to Marrash discloses an electronically programmable metronome having a foot switch for adjusting the tempo over a continuous range without taking hands off an instrument or interrupting playing. A micro-controller is pre-programmed with a metronome click pattern in any selected note duration value. The clicks are produced with different amplitudes and tones so as to produce distinct loud medium and soft-clicks. Headphones, an audio speaker and/or a light emitting diode indicator provide audible and visual cues of the tempo to aid the user.
In U.S. Pat. No. 5,850,048, issued Dec. 15, 1998 to Ruf, a digital read-out electronic metronome is taught which displays the correct beat per measure. The Ruf device includes a keyboard for entry of a musical signature including the number of beats per measure. A liquid crystal display visually informs a user of the correct beat of a measure. The display may be in the form of a graphical representation of a measure with visual indicia highlighting the current beat. Ruf's device is pocket-sized and battery operated.
None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.
SUMMARY OF THE INVENTION
The present invention provides a “Measure Minder” device that visibly and audibly displays the beats in a measure of music being played by a musician and further provides a visual numerical display of the correct measure being played. The device is useful for the purpose of reminding beginning music students of the place to begin as well as maintain playing a selection of music on a sheet of music. In addition, the present invention provides a means for aiding conduction of beginning music students in that the student is visually reminded of the beat, tempo and measure for a selection of music on a sheet of music.
Two display housings are flexibly connected together by one or more plastic hinges such that when the Measure Minder is placed on a conductor's stand, the display of the first housing is viewable to the conductor/instructor and the display of the second display housing is viewable to the musician/music student facing the conductor/instructor. The housing of the Measure Minder holds the metronome electronics and/or batteries to power the Measure Minder.
The metronome electronics cooperates with a keypad on one of the display faces of the Measure Minder housing to start and stop the Measure Minder displays, to adjustably select the display tempo for the beats of each measure, to adjustably select the number of beats per measure, and to adjustably select which measure will be indicated on the displays to instruct the students as to the location on the music sheet that the instructor wants the student to begin playing. For music pieces written with changes in tempo and/or beats per measure, the conductor has the ability to program in those requirements as needed using the keypad. After programming, pressing the start button causes the Measure Minder to proceed through the piece making changes in tempo and/or beats per measure at the programmed points in the music piece.
The Measure Minder housing consists of two display housing parts electrically and mechanically connected together so that the display face of the first display housing is viewable to the instructor and the display face of the second display housing is viewable to the students. The display face of first display housing includes a first liquid crystal display (LCD) (or, if desired, a light emitting diode or LED display) for indicating to the conductor/instructor the measure count of the music being played, a first blinking light display in the shape of a minus sign formed of an LCD segment which indicates to the conductor/instructor the selected number of beats per measure at the selected tempo, and/or a speaker to audibly indicate to the conductor/instructor the number of beats per measure at the selected tempo.
The keypad is provided on the display face of the first display housing. The keypad allows the conductor/instructor to select the tempo, select the number of beats per measure, select the beginning measure count, select the start or stop the displays, program changes in tempo and/or beats per measure, and to turn the Measure Minder power on and off. The switches of the keypad may be provided on a display membrane having a clear window for viewing the LCD displays on the display face of the first display housing.
When an audio beat is desired, the conductor/instructor can plug an amplifier or earphone into the audio output jack of the first display housing and the desired audible beat can be heard.
The display face of the second display housing also includes a second LCD which indicates to the musician/music student the measure count of the composition of music being played and a second blinking light display in the shape of a minus sign formed of an LCD segment to indicate to the musician/music student the selected number of beats per measure at the selected tempo to be played.
A plastic ribbon with flexible conductors or conductive traces thereon connects the displays of the second display housing with the electronic metronome circuit. VELCROTM or other suitable fastening means are adhesively placed on the back face of the first display housing and the and the top surface of the conductor's stand to allow the Measure Minder to be removably secured to the top of the conductor's stand.
The first display housing may also be equipped with a signal transmitter to transmit the beat and measure count signals to a plurality of second display housings fitted with signal receivers, whereby the beat and measure count cam be viewed by persons at remote locations. Any type of transmitter/receiver system capable of sending and receiving the digital beat and measure count signals would be suitable for this purpose.
Accordingly, it is a principal object of the invention to provide an electronic metronome having displays for indicating to a music student and an instructor the number of beats per measure, the number of the current measure being played, and the tempo at which to play.
It is another object of the invention to provide an electronic metronome wherein the tempo, beat, and number of the measure to be played are selectable and indicated to both the students and the instructor.
It is a further object of the invention to provide a portable battery powered electronic metronome wherein the tempo, beat and the number of the measure of a music selection to be played are selectively adjustable for simultaneous display before the student and the instructor.
Still another object of the invention is to provide an electronic metronome that contains two durable plastic or metal cases or display housings wherein one display housing has a large visual display of the measure count for easy viewing by students to remind them of the location to begin and continue playing.
It is an object of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes.
These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.
