Abstract

A Music Note Letter and Symbol Display Device which displays Music Note Letter compositions of Scales for each of the Fifteen (15) Major Keys of: C G D A E B F♯ C♯ C♭ G♭ D♭ A♭ E♭ B♭ and F and for each of the Fifteen (15) Minor Keys of: A E B F♯ C♯ G♯ D♯ A♯ A♭ E♭ B♭ F C G D.

The device also displays Sixteen (16) Types of Chords for each of the Fifteen (15) Chord Letters of: C G D A E B F♯ C♯ C♭ G♭ D♭ A♭ E♭ B♭ and F.

The device can also be used to make musical transpositions from one Key/Scale/Chord to another and is used to identify the Music Note Letter compositions of twelve (12) Intervals for each of the Fifteen (15) Major Keys of: C G D A E B F♯ C♯ C♭ G♭ D♭ A♭ E♭ B♭ and F.

All Music Note Letters are displayed through readout apertures which are located on the face of its Data Retrieval Member.

Claims

1. In a Music Note Letter and Symbol Display Device comprising a data storage member on which are displayed multiple columnar segments of music note letter and symbol combinations where within each said columnar segment are contained three (3) columnar displays which are each uniquely identified by their relative positions within each said columnar segment as left positioned, center positioned and right positioned respectively and where the physical spacing between the said left positioned columnar display and the said center positioned columnar display is equal to the physical spacing between the said center positioned columnar display and the said right positioned columnar display, and where,

the physical spacing between the said columnar displays of said columnar segment is equal to the physical spacing between the columnar displays which are contained within any other columnar segment, and where,

the physical spacing between any two (2) physically adjacent columnar segments is equal to the physical spacing between any other two (2) physically adjacent columnar segemtns, and where,

the physical spacing between any two (2) physically adjacent rows which are contained within any columnar display of any columnar segment is equal to the physical spacing between any two (2) other physically adjacent rows which are contained within any other columnar display which is contained within any other columnar segment, and where,

the music note letter and symbol combinations which are either overtly displayed or covertly implied for all rows within any columnar display are ordered by a musically chromatic relationship wherein the unique music note letter and symbol combination which is either overtly displayed or covertly implied within any unique row which is contained within any unique columnar display has a musical value which is one (1) musically chromatic pitch value higher than either the overtly displayed or covertly implied value defined for a first adjacent row which is contained within the said unique columnar display and which said first adjacent row is relatively positioned below the said unique row, and wherein,

the said unique music note letter and symbol combination which is either overtly displayed or covertly implied for said unique row has a musical value which is one (1) musically chromatic pitch lower than either the overtly displayed or covertly implied value defined for a second adjacent row which is contained within the said unique columnar display and which said second adjacent row is positioned relatively above said unique row, and where,

the musical value which is either overtly displayed or covertly implied for said unique row which is contained within said unique columnar display is identical in musical value to either the overtly displayed or covertly implied musical value or its enharmonic equivalent which is displayed in the same relative row within each of the other two (2) columnar displays which are both contained within the said unique columnar segment which contains said unique columnar display, and where,

either the overtly displayed or covertly implied musical values or their enharmonic equivalents which are defined for said unique row which is contained within all columnar displays within said unique columnar segment are seven (7) chromatic pitch values lower than either the overtly displayed or covertly implied musical values or their enharmonic equivalents which are defined for the same relative row which is contained within the physically adjacent columnar segment which said physically adjacent columnar segment is positioned relatively to the right of said unique columnar segment, and whereby,

the means for the retrieval of music note letter and symbol combination data is provided by positioning over the said data storage member a data retrieval member which is slidably mounted and which contains readout apertures through which music note letter and symbol combinations can be viewed, and where,

within the said data retrieval member are positioned three (3) key apertures which are used to position the said data retrieval member for the retrieval of music note letter and symbol data through the other said readout apertures, and where,

the said data retrieval member is in a position for retrieval of music note letter and symbol combination data through the other said readout apertures when music note letter and symbol combination data is simultaneously displayed through all three (3) said key apertures, and where,

the musical scale readout apertures which are used in the retrieval of music note letter and symbol combinations which define Major and Minor Scales are positioned to function in cooperation with the three (3) key apertures such that the music note letter and symbol combinations which are viewed through the said musical scale readout apertures are retrieved from only the said relative left positioned columnar display of each participating columnar segment, and where,

the unique music note letter and symbol combination displayed through a unique readout aperture for a unique positioning of the three (3) said key apertures defines a unique musical note which is a part of the musical expression of either a musical scale or a musical chord, and where,

the said unique music note letter and symbol combination which is displayed on the data storage member in a unique relative columnar display positioning and viewed through said unique readout aperture is used to express a musical note which is a part of another musical expression of either a musical scale or musical chord by display through a second readout aperture which is positioned in the same relative row position and the same relative columnar display positioning as said unique readout aperture and which said second readout aperture is positioned on the said data retrieval member relatively to the left of said unique readout aperture, and where,

each music note letter and symbol combination which is displayed on the said data storage member is uniquely located in a relative left positioned or center positioned or right positioned columnar display and defined row positioning within a unique columnar segment whereby each said music note letter and symbol combination is defined for cooperative use only through apertures which have been uniquely defined for functioning within the same relatively positioned columnar display and defined row positioning on the said data retrieval member, and where,

the musical note letter and symbol combination which is displayed through a readout aperture is the proper musically correct notation which will define a musical note value used in the musical expression of either scale or chord information for Major or Minor musical keys.
