傳統嗩吶的管身有8個音孔，由右手的食指、中指、無名指、小指，以及左手的大拇指、食指、中指、無名指來按音。發音的方式，是由嘴巴含住蘆葦製的哨子吹氣使之振動發聲，經過管身及碗的振動及擴音而發出聲音。The body of the traditional suona has 8 sound holes, and the notes are played by the index finger, middle finger, ring finger, and little finger of the right hand, and the thumb, index finger, middle finger, and ring finger of the left hand. The method of pronunciation is to hold a reed whistle in your mouth and blow air to make it vibrate and produce sound. The sound is produced through the vibration and amplification of the pipe body and bowl.
傳統嗩吶按音域及樂器大小可分為小嗩吶（又稱海笛）、高音嗩吶、大嗩吶，其中可再分為各種調性的嗩吶，如G調小嗩吶、F調小嗩吶、D調高音嗩吶、C調中音嗩吶、G調大嗩吶等等﹝調性是指放開最下面3孔時所吹出的音﹞。傳統嗩吶的常用音域為17度音，最常用的D調高音嗩吶，音域由低音A至高音a，最高音b，則較不常用。Traditional suona can be divided into small suona (also known as sea flute), treble suona and large suona according to the range and size of the instrument. It can be further divided into suona in various tones, such as small suona in G key, small suona in F key, and D key. Treble suona, alto suona in C, large suona in G, etc. (The tonality refers to the sound played when the bottom three holes are released). The commonly used range of traditional suona is 17 degrees. The most commonly used treble suona in D key has a range from low A to high a, and the highest note b is less commonly used.
傳統的嗩吶的按孔則是橢圓形的樣子，採用七孔律。The pressing holes of the traditional suona are oval-shaped and adopt the seven-hole rule.
