In philately there are collections and thematic series.
Thematic is a term that can function as a noun or adjective. In the first case, it refers to the theme or the great variety of themes and issues that characterize a fact or phenomenon.
Some examples of its use can be seen below: «This book deals with the issue of respect for the rights of minorities in a democracy» , «The government of Spain shows a special interest in the issue of gender violence» , «The Bedroom decoration follows a marine theme, with colors and elements typical of the ocean .
thematic vowel
The thematic vowel is known as the inflectional morpheme (the minimum portion capable of expressing the meaning of the root of a word) that aims to indicate to which category the lexeme (the root) belongs, regardless of whether it works. or not as a verb. It serves to distinguish between the different conjugations, of which there are three in Spanish, and the theme with which each verb corresponds, which are explained below:
* present theme : which gives rise to the forms of the indicative, the subjunctive and the imperative, the three modes recognized by our grammar ;
* past tense theme : serves to construct the past imperfect and the simple perfect of the indicative mood, the imperfect and future of the subjunctive mood and, on the other hand, the gerund and the participle;
* future theme : allows the formation of the future of the indicative, the infinitive and the conditional. They are the three conjunctions "ar", "er" and "ir", defined in that order and accompanied by the corresponding ordinal adjective ( first conjunction , etc.).
The concept in philately
For philately , the theme is linked to a series , an issue or a collection of stamps.
In each theme, a single theme or motif is used: “The theme of this broadcast is Olympic sports,” “The animal-themed engravings show a figure that many scholars have identified as a bison.”
The attractions of a theme park revolve around the same concept, motif or argument.
The theme as a concept of an amusement park
A theme park , on the other hand, is a term that allows you to name a set of attractions organized around the same plot line. It could be said that it is a synonym for amusement park (also called amusement park ), with one fundamental difference: it specializes in a single theme.
In Argentina , more precisely in the national capital ( Buenos Aires ), one of the most important theme parks is Tierra Santa , dedicated to religion . Inside it is possible to tour the replicas of the streets of Jerusalem and observe different stages of the life of Jesus Christ .
A very important theme park in Spain is Terra Mítica , which is located in Benidorm ( Alicante ). This place is based on the ancient civilizations of the Mediterranean , such as Egypt , Greece and Rome , among others.
The notion in music
In musical theory, thematic transformation is a technique that consists of developing the theme (or leitmotif ) through change, using permutation (alteration of the order of its parts), augmentation (prolongation of the time that a note lasts or repetition of a theme in larger values, which is usually very common in the fugue), diminution (presentation of a theme in values smaller than those of its exposition, used in the contrapuntal style) and fragmentation (repetition of a recognizable segment of the motif original, maintaining or not the rhythm and melody).
Its authors and main representatives were Hector Berlioz and Franz Liszt and it is, in essence, a variation, since it consists of repeating a basic theme from the beginning to the end of a work. However, it differs from this other technique by giving each transformation its own life , detaching it from the original theme. Ludwig van Beethoven was another of the great composers to make use of thematic transformation, and this can be seen in his famous Ninth Symphony.
