Old Time and Celtic songs are about whiskey, food and struggle. Bluegrass songs are about God, mother and the girl who did me wrong. If the girl isn’t dead by the third verse, it ain’t Bluegrass. If everyone dies, it’s Celtic. 

A Bluegrass band has between 1 and 3 singers who are all singing about an octave above their natural vocal range. Most Old Time and Celtic bands have no singers at all. If a Celtic band has a singer, it is usually either a bewhiskered ex-sailor, or a petite soprano. A Bluegrass band has a vocal arranger who arranges three-part harmonies. In an Old Time band, anyone who feels like it can sing or make comments during the performance. In a Celtic band, anyone who speaks during a performance gets ‘the look.’ Celtic songs are preceded by a call for silence and a detailed explanation of their cultural significance. 

Bluegrass tunes & songs last 3 minutes. Old Time and Celtic tunes & songs can be any length, and sometimes last all night. 

The Instruments 

Banjo 

Celtic banjos have 4 strings, Old Time and Bluegrass banjos have 5. An Old Time banjo is open-backed, with an old towel (probably never washed) stuffed in the back to dampen sound. A Bluegrass banjo has bell bronze “mastertone” tone ring and a resonator to make it really loud. An Old Time banjo weighs 5 pounds, towel included, and a Bluegrass banjo weighs 40 pounds. A Bluegrass banjo has 24 frets. An Old Time banjo needs no more than 5 frets, and some don’t have any. 

Fiddle 

The Bluegrass fiddler paid $10,000 for his fiddle at the Violin Shop in Nashville. The Celtic fiddler inherited his fiddle from his mother’s 2nd cousin in County Clare. The Old Time fiddler got his for $15 at a yard sale. 

Celtic and Bluegrass fiddles are tuned GDAE. An Old Time fiddle can be in one of a hundred different tunings. Old Time fiddlers seldom use more than two fingers of their left hand, and use tunings that maximize the number of open strings played. Celtic and Bluegrass fiddlers study 7th position fingering patterns with Isaac Stern, and take pride in never playing an open string. An Old Time fiddle player can make dogs howl & incapacitate people suffering from sciatic nerve damage. An Old Time fiddle player only uses 1/8 of his bow. The rest is just there for show. 

Guitar 

An Old Time guitarist knows the major chords in G and C, and owns a capo for A and D. A Bluegrass guitarist can play in E-flat without a capo. The fanciest chord an Old Time guitarist needs is an A to insert between the G and the D7 chord. A Bluegrass or Celtic guitarist needs to know chords like “C#aug+7-4.” A Celtic guitarist keeps his picks in his pocket. Old Time guitarists stash extra picks under a rubber band around the top of the peg head. Bluegrass guitarists would never cover any part of the peg head that might obscure the inlays on their $4,000 Martin.

Mandolin 

It’s possible to have an Old Time or Celtic band without a mandolin. However, it is impossible to have a true Bluegrass band without one. Old Time and Celtic mandolin players play abused, vintage ‘A’ model instruments bought at garage sales, which is fine, because you can’t hear them anyway. Bluegrass mandolin players use ‘F’ models that cost $100 per decibel. 

Bass 

A Celtic band never has a bass, while a Bluegrass band always has a bass. An “old” Old Time band doesn’t have a bass, but “new” Old Time bands seem to need one for reasons that are unclear. A Bluegrass bass starts playing with the band on the first note. An Old Time bass, if present, starts sometime after the rest of the band has run through the tune once depending on the player’s blood alcohol content. Bluegrass bass players play all over the neck. An Old Time bass player may only use his left hand to keep the bass from falling over. A Bluegrass bass is polished and shiny. An Old Time bass is often used as yard furniture. 

Arrangements 

Except for the guitar and bouzouki, all the instruments in a Celtic band play the melody all the time. In an Old Time band, anyone can play either melody or accompaniment at any time. In Bluegrass bands, one instrument at a time solos, and every else plays accompaniment. 

Bluegrass bands have carefully mapped-out choreography due to the need for access to the one microphone on solo breaks. If Old Time and Celtic band members move around, they tend to run into each other. Because of this problem (and whiskey) Old Time and Celtic prefer to sit down when performing, while a Bluegrass band always stands. Because they’re sitting, Old Time and Celtic bands have the stamina to play the same tune for 20 minutes for a square or contra dance. The audience claps after each Bluegrass solo break. If anyone claps near an Old Time or Celtic band, it confuses them, even after the tune is over. 

Personalities—Stage Presence 

Bluegrass band members wear uniforms, such as blue polyester suits with gray Stetson hats. Old Time bands wear jeans, sandals, work shirts and caps from seed companies. Celtic bands wear tour tee-shirts with plaid touring caps. All this headwear covers bald spots. 

Women in Bluegrass bands have big hair and Kevlar undergarments. Women in Old Time bands jiggle nicely under their overalls. The women in Celtic bands are either lassies with long skirts and lacey, high collars or wenches in apple-dumplings-on-a-shelf bodices and leather mini-skirts. 

A Bluegrass band tells terrible jokes while tuning. An Old Time band tells terrible jokes without bothering to tune. Bluegrass band members never smile. Old Time band members will smile if you give them a drink. A Celtic band is too busy drinking to smile, tune or tell jokes. Celtic musicians eat fish and chips, Bluegrass musicians eat barbecue ribs, and Old Time musicians eat tofu and miso soup. 

Bluegrass musicians have mild high frequency hearing loss from standing near the banjo player. Old Time musicians have moderate high frequency hearing loss from sitting near the fiddler. Celtic musicians have advanced hearing loss from playing in small pubs with all those fiddles, banjos, tin whistles and bodhrans.

Festivals 

A Celtic band travels in an actual Greyhound bus with marginal air conditioning and then catches a ride from the bus stop to the festival any way they can. A Bluegrass band travels in an old converted Greyhound bus that idles in the parking lot all weekend with the air conditioner running full blast, fumigating the county with diesel exhaust. An Old Time band travels in a rusted-out 1965 VW microbus that blows an engine in North Nowhere, Nebraska. Bluegrass players stay on the bus and Celtic musicians stay at the nearest Motel 6, while Old Time musicians camp in the parking lot. 

Cases

The Celtic band has their name on their instrument cases. The Bluegrass band’s name and Inspirational Statement are painted on both the side of the cases and the front of the bus in script lettering. Old Time cases are covered with stickers don’t make any sense (e.g. ‘Gid is My Co-Pilot’)
