ทฤษฎีดนตรีสากลเบื้องต้น (โดยครูสมเกียรติ เวชภูติ)

The correct answer is "ชาร์ฟ". The symbol (#) is commonly known as a "hash" or "pound" sign in English, but in Thai language, it is commonly referred to as "ชาร์ฟ" (chaaf).

The correct answer is "แฟล็ท".

The correct answer is "แฟล็ท" because a "แฟล็ท" is a musical symbol that indicates a decrease in volume by half. It is used to instruct the performer to play or sing the note at a softer dynamic level.

The correct answer is "โด" because it is the Thai translation for the musical note "Do" in English.

The correct answer is that the "ตัวขาว" note has a length equal to half of the "โน้ตตัวกลม". This means that the "ตัวขาว" note is half the duration of the "โน้ตตัวกลม".

We can determine the short-long duration of a sound or rhythm, also known as tempo, from the characteristics of the note itself. In this case, the answer states that the characteristic of the note is what allows us to determine the short-long duration. The other options, such as "line 5," "few lines," and "stopped note," do not provide any information about the duration of the sound. Therefore, the correct answer is the characteristic of the note.

The correct answer is "บรรทัด 5 เส้น" because it refers to the staff notation, which is a system of five horizontal lines on which musical notes are written. By reading the notes on the staff, we can determine the pitch of the musical note, whether it is high or low. The other options listed, such as key signatures, musical instruments, and different types of notes, do not directly indicate the pitch of the musical note.

The question asks how many notes are there in international music. The correct answer is 7, which refers to the seven notes of the diatonic scale: do, re, mi, fa, sol, la, ti. These notes are the building blocks of music and are used in various combinations to create melodies and harmonies.

The correct answer is "ชาร์ฟ" because the term "ชาร์ฟ" refers to a symbol in music notation that indicates to play the note with a half-step higher pitch. This means that when this symbol is used, the note will have a higher sound by half a step.

The word "บรรทัด" means "line" in Thai, and "เส้น" means "line" as well. Therefore, the correct answer "บรรทัด 5 เส้น" translates to "line 5".
