The standard harp size is a topic of interest for many musicians and enthusiasts of the harp, an instrument with a history dating back to ancient cultures. Harps come in a wide variety of sizes, ranging from small folk harps to large concert grand harps. So, what is considered the standard harp size?

Before diving into the specifics, it's essential to understand that there isn't a universally accepted definition of a standard harp size. Harps are classified by the number of strings they have, and the term 'standard' can vary depending on the context and the type of harp being discussed. However, for the purposes of this article, we'll focus on the pedal harp, a common type in orchestras, and the lever harp, a popular choice for folk and Celtic music.

Pedal Harp
The pedal harp is a large harp that typically has seven pedals, each controlling the pitch of all the strings that are tuned to the same note. It's the most common harp used in orchestras and has a rich, resonant sound. When people refer to a standard harp in an orchestral context, they're usually talking about the pedal harp.

Standard pedal harps usually have about 47 strings, tuned in four seven-octave chromatic scales. The most common standard pedal harp size is around 7 feet tall, with a width of about 3 feet, and a depth of around 2 feet. This size allows for a wide range of dynamics and tonal colors, making it a versatile instrument in the orchestra.
String Range

As mentioned, standard pedal harps have about 47 strings. The pedal harp's extensive string range allows it to play music originally written for other instruments, such as the piano, and to perform a wide repertoire of original harp music. The lowest string is tuned to G#, and the highest is tuned to G#7.
The pedal harp's extensive range is one of the reasons it's such a versatile instrument. It can play both high, delicate melodies and low, resonant notes, making it a valuable addition to any orchestra.
Pedal Mechanism

The pedals on a standard pedal harp allow for a wide range of tonal possibilities. Each pedal raises or lowers the pitch of all the strings that are tuned to the same note. This allows harpists to play chords and progressions that would be impossible on a harp without pedals.
Each pedal has a different effect on the strings. For example, the C pedal raises the pitch of all the C notes by half a step, and the G pedal raises the pitch of all the Gs by a whole step. This allows harpists to create complex chords and to modulate the key of a piece without having to retune the instrument.
Lever Harp

The lever harp, also known as the Celtic harp or folk harp, is smaller and more portable than the pedal harp. It's widely used in folk and Celtic music and has a unique, delicate sound. When discussing standard harp sizes in folk music contexts, people usually refer to the lever harp.
Standard lever harps typically have about 34 to 36 strings, tuned in three seven-octave chromatic scales. They're usually around 4 feet tall, with a width of about 1.5 feet, and a depth of around 1 foot. This size makes the lever harp easy to transport and suitable for solo performances and small ensembles.







Lever Mechanism
Lever harps have a mechanism that allows the player to raise or lower the pitch of each string individually. This is done using levers that are attached to the body of the harp. The levers raise or lower the pitch of the string by narrow wooden rods calledardon bars.
unlike the pedal harp, the lever harp only has seven levers, each controlling all the strings tuned to one of the seven diatonic notes. This makes it easier to play, but it also limits the harp's range of tonal colors compared to the pedal harp.
String Range
As mentioned, standard lever harps have about 34 to 36 strings. The string range of a lever harp is typically three and a half to four octaves. The lowest string is tuned to C, and the highest is tuned to C#7 or C8.
The lever harp's smaller size and more limited range make it suitable for a different style of music than the pedal harp. It's often used for solo performances and small ensemble playing, and it has a more intimate, delicate sound than the larger pedal harp.
In conclusion, the standard harp size can vary depending on the type of harp and the context in which it's being used. Pedal harps are typically around 7 feet tall, with a wide range of strings and a pedal mechanism that allows for a wide range of dynamics and tonal colors. Lever harps, on the other hand, are smaller and more portable, with a mechanism that allows for a more limited range of tonal possibilities. Both types of harps are essential to the music they play and have their unique sounds and functions in the musical world.
