DE2901785A1 - Slide rule music teaching aid - has openings indicating transposition between keys and notation using scale and giving pitch and intervals - Google Patents

Abstract

The music teaching aid for home or school use has an outer casing holding a slider in the manner of a slide rule. On the outside of the casing is a set of openings through which can be read various types of musical information. The slider can be moved to select a certain musical note in a line of holes to obtain corresponding information. A minor note is shown in a window and a transposed indication in a window underneath, the appropriate scale being shown in a slot adjacent to a key sign followed by a whole octave arranged on ledger lines. Further information for obtaining chords and harmonies is also indicated.

Description

Ref. Chord slider for the range of

Musicology Description: The invention, in the further text with Called a chord slider, the underlying idea is that it is easy to use To create learning and teaching aids, both for school lessons and for self-study.

The chord slider presented here puts the learner in the Ability to ensure that what has been learned is correct as a whole or in individual steps to check. The options for the settings and the resulting displays in the fields of the envelope comprise a substantial part of elementary music studies, which was additionally supplemented by informat ve labels and examples.

But not only the learner under the guidance of a music teacher, but also the hobby musician, who was not instructed in music theory, should also make the laws of music science understandable with the chord slider, understand the way of their construction and depending on your talent and talent yourself dare to do something.

The desire for more knowledge, even if it is only possible through self-study is so sure to be awakened because many things are no longer so complicated and difficult appears.

The notation of an accompaniment for guitar or other instruments to a melody, for the gifted but music-ignorant it becomes with the chord slider certainly made easier.

The chord shifter is musical knowledge in the smallest of spaces, available at all times and what has been learned can be easily checked within the scope of its possibilities. He is one very good complement to today's literature of the 1st level of education.

Solution: In the present conception, the slide consists of one Cover and an internal sliding part. The cover consists of a front and back and separates the two tones major and holl.

The adjustable slide (inner part) was also double-sided used after the same division of major and minor.

In the basic position, sliders in the cover, appear in the fields C major or A minor.

Fig. 1, field 1 and Fig. 2, field 1 (dark point under C or a).

The key appears again in field 2, Fig. 1 and Fig. 2.

Fields 3 and 4 remain empty as there are no accidentals in these cases belong to the scales.

The scale in the bottom row of notes is output from the root note in the hole matrix field 5 in Fig. 1 of C and in Fig. 2 of a and all Triads in this key.

The sections in field 6, Fig. 1 and Fig. 2 indicate the sound characteristics Minor (M), major (D), ladder levels 1, 2, 3 ... 7 and the functions main, Secondary sounds.

E.g. tonic (T), subdominant (S), dominant (D), tonic parallel (Tp), subdominant parallel (Sp), dominant parallel (Dp).

Field 7, Fig. 2 denotes harmonic minor, which is indicated by the conductor Level 7-8 stands. Due to the immediate vicinity of fields 6 and 7 in Fig. 2 the effects of the lead tone on the sound change are particularly clear made.

1st example If the slider is adjusted, for example, so that in field 1 (Fig. la) D appears, the parallel one appears on the minor side Key of B minor on (Fig. 2a). The key (field 2) the type and number of accidentals (Field 3) and the position of the displacement symbols (field 4) become visible (c sharp and f sharp are marked as dots in the lines). At the same time, the shifts 1. Three-note step from C to D (Fig. 1a) or from a to h (Fig. 2a). The triad who does not belong to this scale becomes free. A whole is shown in each case Octave (field 5).

Move the designations in field 6 (Fig. 1a and Fig. 2a) itself, so that the sounds, levels and functions of the newly set scale be assigned. The leading tones for major and harmonic minor (Fig. La field 6 right for major and field 7 Fig. 2a right for harmonic minor) also change and match the set scale.

The example described represents 15 other options on each Side of the chord slider.

The chord slider, as described above, also comes with a Equipped runner, which can be moved in a guide (Fig. 3 and Fig. 4). With it, all church tones can be played on the major side and off on the minor side the pure minor can be derived melodically minor.

In Fig. 3, the runner and slider are in their basic position, i.e. 0 major.

The runner, for the determination of the church tones, stands so that Jonisch cuts the basic C major chord. In this position there are 12 church keys based on the C major ladder. Far left in the runner hypojonic up to to Aeolian, the highest church scale.

2nd example: Would you like a certain keynote on any keynote? To build up the church scale, proceed as follows: Determination in E-Doric: The rotor is adjusted so that Dorian C intersects with the vertical line e. The slide (inner part) is adjusted so that the 1st chord is in the note matrix Field 5 goes through the vertical line of Jonisch 1.

In field 1 of Fig. 3g is marked D, i.e. that e-Doric on the base of D major has to be built up, i.e. a ladder with f sharp and c sharp. . Of the After this setting, runner has the other, 1 church tones on the Base of D major at the same time determined. It is only to be noted that the Runner sets the starting note. From there onwards, levels 1-7 must be built up.

It should be noted that the same note matrix also applies to D flat major.

D flat major has B flat, including Eb. In that case it would be Doric, but not in E-Doric as intended. Let in respect of these rules the church tones are based on every cirundal tone, up to C sharp major 7 # or C @ b major 7b. The @@ @@ regularity of the semitone steps and the characteristic feature @ for F = Finalis and R = Reperkuss @ onst @ n remain in accordance with the scale levels always respected.

Fig. 4. shows the change from the pure minor to the melodic minor am Example b minor.

The bishop stands so that line 1 intersects the basic chord.

Since the 6th and 7th leaflet levels are raised in the melodic minor, it changes Every triad from level 2. The lettering in the runner indicates how the intervals from level 2 onwards are to be dealt with by the fundamental tone of the ladder level. E.g. level 2 from g, fifth from cd becomes g sharp.

Level 3 from a, fifth of d becomes aids. Level 4 from g, third of e becomes g sharp etc.

Below that are the sound characteristics D for major, etc.

Down the ladder, the increases must be resolved again, since in The accuracy of the notes is essential for the singers in the song composition is increased.

This example also stands for all keys in the minor gender.

Figs. 5 and 6 show the internal slide.
