What it is

A chorded zither: a wooden box with 36 (sometimes up to 47) strings and 12, 15 or 21 chord bars that press felt pads on to the strings, damping all but the notes of the chord. Played by strumming or picking, in country, folk and old-time music (Mother Maybelle Carter). Oscar Schmidt is the main maker.4,3

Range

F2 to C6487.3 Hz – 1.05 kHz

36-string chromatic model; the lowest octave has gaps

The sound

The strings drive the soundboard; the body has a guitar-like soundhole. The back of a good autoharp is "surprisingly full and rich" and has little of the chord-bar and pick noise.4,1

Where the sound goes

From the front soundboard and soundhole, and from the back, which is richer and quieter in mechanical noise.1,2

About the range

A 36-string chromatic autoharp spans three and a half octaves, F2 to C6, though it is not fully chromatic across the range (the lowest octave has gaps).4

How loud

Sound pressure level measurements as published. Different kinds of figure (a playing level, a peak, a dose at the player's ear) can't be compared with each other, and neither can figures at different distances.

Peaks
95 dBat the back of the instrument1

Lindsay Haisley measured a maximum of about 95 dB at the back of a good autoharp (distance and weighting not given; informal measurement).1

Recording it

Paul Stamler: from the front with a KM 84 or MK-012; if the player sings, one mic for both, or a miniature lavalier such as a DPA 4099 on the player's shirt to pick up the back; the back pickup "limits the mechanical noise and gives a fullness of sound" closer to what the player hears. Haisley's technique is the same idea: a lavalier on the strap behind the top of the instrument; his front mic adds the "picky" sound so it still sounds like an autoharp.2,1

Studio and stage

Clip-on

The 3 setups behind this: placement and quotes
  • Clip-on Countryman B3
    back mic, strap-mounted
    A very small omnidirectional microphone from Countryman, model B3, fits on the strap, picking up the back of the harp.1
  • Multi-mic plan lavalier on strap picking up the back of the instrument, plus front mic on stage
    back + front mic
    A lavalier attached to my strap, picking up the sound from the back of the instrument; on stage I add a front mic.1
  • Clip-on DPA 4099
    clip-on, on shirt, picks up back
    Attach a miniature lavalier like the DPA 4099 to the player's shirt so it picks up the instrument's sound from the back.2

On stage

Clip-on

The 2 setups behind this: placement and quotes
  • Clip-on Shure SM84
    back mic, clipped to strap
    For years I have been using a venerable Shure SM84 as a back mic, but it is fiddly to keep in the right position.1
  • Close high-quality directional mic on a stand, with a sound engineer
    front, stand
    The best way to amplify an autoharp for public performance is with a high-quality directional mic pointed at it.3

The 1 setup behind this: placement and quotes

On stage

Haisley used a Shure SM84 clipped as the back mic for years (unidirectional, fiddly to aim), then moved to a Countryman B3 omni on the strap (normal sensitivity is enough at 95 dB). The Creek Don't Rise article says the best sound is always "a quality separate microphone plugged into a good system"; magnetic pickups ignore chord-bar clatter and pick clack but lose the wood tone; piezo and attached mic pickups are the other options; attached condensers give the truest sound but feed back more. If the singer holds the autoharp upright, a vocal mic can be shared.1,3

Problems to watch

Chord-bar clatter, pick clack and handling noise on a front mic or contact pickup; feedback on attached mic pickups.1,3
