Problems solved by technology

[0002] In the learning and application of music theory, it is often necessary to convert the first key and the fixed solfa method. At present, in the process of transposing and transposing, the conversion of whole tone and semitone combination relationship of different tonality can only be calculated and converted by the user. time consuming and error prone

Embodiment 1

[0052] See attached Figure 1-3 , read the relationship between the fixed roll call and the first roll call in E natural major:

[0053] S1, install the conversion ruler: insert the inner ruler 1 into the outer ruler 2, and the inner ruler 1 can reciprocate along the length direction of the outer ruler 2;

[0054] S2, matching corresponding reference: observe through the reading hole 3 corresponding to the fixed roll call (E natural major) of the target tone on the outer ruler 2, when the first tone roll name of the target tone level on the inner ruler 1 (1 on the inner ruler 1 tone) is aligned with the fixed roll name (E natural major) of the target tone on the outer ruler 2, stop moving the inner ruler 1 and the outer ruler 2, and then the rest of the first tone roll names on the inner ruler 1 are matched to One tone is fixed roll call, and it is displayed in the corresponding reading hole 3 at the same time, that is, the 1st tone (do), the 2nd tone (re), the 3rd tone (mi),...

Embodiment 2

[0057] See attached Figure 4-6 , read the relationship between the fixed pentatonic mode of the E levy and the roll call of the first tone:

[0058] S1, install the conversion ruler: insert the inner ruler 1 into the outer ruler 2, and the inner ruler 1 can reciprocate along the length direction of the outer ruler 2;

[0059] S2, matching and corresponding reference: observe through the reading hole 3 corresponding to the fixed roll call of the target tone (the tonic of E major) on the outer scale 2, when the first roll call of the target tone level on the inner scale 1 (so on the inner scale 1 (5) Tones) When aiming at the fixed roll call of the target tone on the outer ruler 2 (the tonic of E major), stop moving the inner ruler 1 and the outer ruler 2, and then the rest of the first tone roll names on the inner ruler 1 will be They are all matched to a pitch fixed roll call, and displayed in the corresponding reading hole 3 at the same time, that is, 1 (gong), 2 (quotient)...

Abstract

The invention discloses a conversion ruler for movable-do and fixed-do converting and a use method of the conversion ruler, and the method comprises the steps: displaying the positions of movable-do with different tone levels in a matching manner on a ruler surface of an inner ruler according to the minor second relation of semitone and the major second relation of whole tone; fixed-do positions with different tones are displayed on a plurality of black key fixed-do corresponding areas and a plurality of white key fixed-do corresponding areas on an outer ruler corresponding to the arrangement mode of a piano keyboard, reading holes are formed in each black key fixed-do corresponding area and each white key fixed-do corresponding area in a penetrating mode, and the inner ruler or the outer ruler is moved, the movable-do of the target tone level on the inner ruler is aligned with the fixed-do of the target tone on the outer ruler, the movable-do of other tone levels on the inner ruler can be automatically aligned with the fixed-do of other tones on the outer ruler, and finally the needed movable-do and the needed fixed-do are read through the reading hole. The invention discloses the conversion ruler for movable-do and fixed-do converting and the use method thereof, calculation is not needed, operation is convenient, time and labor are saved, and the result is accurate.

Description

technical field [0001] The invention relates to the technical field of music auxiliary tools, and more specifically relates to a conversion ruler for converting first-tone solfa and fixed solfa and its use method. Background technique [0002] In the learning and application of music theory, it is often necessary to convert the first key and the fixed solfa method. At present, in the process of transposing and transposing, the conversion of whole tone and semitone combination relationship of different tonality can only be calculated and converted by the user. Time-consuming, labor-intensive and error-prone. [0003] Therefore, it is an urgent problem for those skilled in the art to provide a conversion ruler for the first-tone solfa and fixed solfa conversion that does not require calculation and can intuitively see the relationship between the first-tone solfa and the fixed solfa, and its use method. Contents of the invention [0004] In view of this, the present inventi...
