10hole

10hole refers to a type of diatonic harmonica, specifically one with ten holes. This is the most common design for a harmonica and is used across a wide variety of musical genres including blues, folk, country, and rock music. The ten holes allow for a range of notes, typically two octaves.

Each hole on the harmonica can produce multiple notes depending on whether the player is blowing air out or drawing air in. A standard 10-hole diatonic harmonica is usually tuned to the key of C, but they are available in all twelve keys. The layout of the notes is arranged in a specific pattern, allowing for various scales and chord voicings.

The 10-hole harmonica is often referred to as a "blues harp" due to its prominence in blues music. Its compact size and portability make it a popular instrument for both beginners and experienced musicians. Techniques such as bending notes, vibrato, and overblowing are essential for expressive playing on this instrument. The versatility and distinctive sound of the 10-hole harmonica have cemented its place in popular music.
